How many rooms should I block for my wedding?

Block conservatively, because empty rooms can cost you through attrition fees while extra rooms don't. A common approach is to reserve rooms for roughly a third of your out-of-town guest count, then add more later if they fill up. It's almost always easier to expand a block than to shrink one, and most contracts require 80-90% of blocked rooms to be booked or you owe the difference. Ask the hotel whether they offer a no-commitment courtesy block if your guest count is still uncertain.

What is minimum pickup in a hotel room block contract?

Minimum pickup is the percentage of your blocked rooms that guests must actually book, typically 80-90%. Fall below it and you owe the difference, since the hotel took those rooms off the market for you. On a 30-room block at 85% pickup, you'd need about 26 rooms booked. Always confirm the exact percentage in writing and run the worst-case math before signing, because pickup is the clause that decides whether you get hit with attrition fees later.

What are attrition fees and how much do they cost?

Attrition fees are what the hotel bills you when guests don't fill the block. If you miss your pickup threshold, the hotel charges you per empty room, sometimes at the full nightly rate rather than your group rate. On a block at $189 a night, falling five rooms short could cost around $945 for one night or nearly $1,900 across two. Ask whether attrition is charged at the group rate, and whether rooms the hotel resells reduce what you owe.

How do I get free comp rooms with my block?

Hotels commonly offer one free room per 10-20 booked, but only if you negotiate it in writing first. A sales rep won't always volunteer it, and a verbal promise is worthless when the invoice arrives. Ask specifically about the comp ratio, when the free room is applied, and whether you can take it as a room or as credit toward the bill. Getting it in the contract as a line item can quietly cover your own wedding-night suite.

What happens if I cancel my hotel room block?

Canceling the block entirely can trigger a penalty of 50-100% of the estimated room revenue, meaning all the rooms across all the nights at your contracted rate. On a 30-room, two-night block at $189, that estimated revenue tops $11,000, so a 50% penalty exceeds $5,500. Fair contracts use a sliding scale that charges less the earlier you cancel. If the contract lists a flat 100% penalty regardless of timing, push back on it before signing.

6 Things Your Hotel Room Block Actually Commits You To

A hotel room block sounds simple until you read the contract. Here are 6 hidden hotel room block costs to check before you sign, and what they can cost you.

You picture it as the easy part. You call the hotel down the road from your venue, tell them you're getting married, and they hold a batch of rooms for your guests at a friendly rate. Everyone books, everyone shows up, done. Then the sales rep emails you a three-page contract with words like "attrition" and "minimum pickup," and you realize a room block is not a favor the hotel is doing for you. It's a commitment you're signing, and some of the lines in it can cost you real money.

This is one of the most overlooked contracts in the whole planning process. It doesn't come with the drama of a photographer deposit or the sticker shock of a catering minimum, so couples skim it and sign. Then 30 days before the wedding, they get a bill for rooms nobody booked. Here are the six things your block actually commits you to, what each one can cost, and exactly what to ask before you sign.

1. Minimum pickup: you're on the hook if guests don't book

The single most important clause is the one most people miss. Most contracts require 80-90% of blocked rooms to be booked, or you owe the difference. This is called "minimum pickup," and it means the hotel isn't holding those rooms out of generosity. They're taking rooms off the open market for you, and they expect nearly all of them to sell.

Say you block 30 rooms at $189 a night for two nights. If your contract sets pickup at 85%, you need roughly 26 of those rooms booked. Fill 20 and you haven't just left some rooms empty, you've technically fallen short of your commitment, and the hotel can bill you for the gap.

how to protect yourself

Block conservatively. It's far easier to add rooms later than to be penalized for empty ones.
Ask for a "courtesy block" instead of a "contracted block" if your guest count is uncertain. A courtesy block holds rooms with no financial commitment, though hotels don't always offer it.
Get the exact pickup percentage in writing, and do the math on the worst-case number before you sign.

2. Attrition fees: the empty-room bill

Minimum pickup is the rule. Attrition is the punishment. If guests don't fill the block, the hotel bills you per empty room at the full nightly rate. Not the discounted group rate you negotiated, the full rate.

This is where a room block quietly turns into a four-figure surprise. Back to the 30-room example. If you fall five rooms short of your pickup requirement and the full nightly rate is $189, that's roughly $945 for a one-night gap, or close to $1,900 across two nights, for rooms nobody slept in. You're paying for air.

Read the attrition clause slowly and ask three questions:

What percentage triggers a fee, and is it measured per night or across the whole block?
Is attrition charged at the group rate or the full rack rate? (Push for the group rate.)
Can unbooked rooms be resold, and if the hotel resells them, does that reduce what I owe?

That last point matters. Some contracts let the hotel keep your attrition fee and resell the room, collecting twice. A fair clause credits you for any room the hotel manages to sell to someone else.

3. The cutoff date: after this, the rate is gone

Every block has a cutoff date, and it's usually 30 days out. After that, any rooms your guests haven't claimed get released back to the public, often at a higher rate. Your Aunt Linda who waited until two weeks before the wedding to book? She may find the block is closed and the only rooms left are $50 more a night.

The cutoff creates two problems at once. It's the deadline that decides your pickup number (so it directly affects whether you owe attrition), and it's the moment your guests lose their discount. Both are reasons to communicate the date loudly and early.

make the cutoff work for you

Put the cutoff date on your wedding website, your invitations, and any group text. Repeat it more than you think you need to.
Ask whether the hotel will honor the group rate for late bookings if rooms are still available. Some will, informally.
If you can, negotiate a cutoff closer to the wedding (21 days instead of 30) to give slow bookers more runway.

4. Comp rooms: free, but only if you ask in writing

Here's the one that works in your favor, if you claim it. Hotels offer 1 free room per 10-20 booked, but only if you negotiate it in writing first. This is your comp room, and it's a genuine perk. Block 20 rooms and you might earn a free night for yourselves or a night to hand to out-of-town parents.

The catch is that comp rooms vanish if you don't get them in the contract. A sales rep will not volunteer it, and a verbal "yeah, we usually do that" is worth nothing when the final invoice arrives. If the comp isn't a written line item, assume it doesn't exist.

Ask specifically: at what ratio do comp rooms accrue, when do they get applied, and can the comp be taken as a room or credited toward the bill? Getting this in writing can quietly cover your own wedding-night suite.

5. Rate parity: when guests find it cheaper online

You negotiated a special group rate, so it should always be the best deal, right? Not necessarily. If a guest finds the same room cheaper online, your contract may not protect them or you. Hotels run flash sales and third-party discounts constantly, and a guest who spots a lower price on a booking site will (understandably) be annoyed that your "special" block rate cost them more.

This creates awkwardness you don't need. Guests feel like the block was a bad deal, and there's nothing in a standard contract that forces the hotel to match a public price for your group.

what to ask for

A rate-parity or "best available rate" clause stating your guests won't pay more than the hotel's public rate during your dates.
Confirmation of what the group rate actually includes. Sometimes the block rate bundles parking, resort fees, or breakfast that the cheaper online rate does not, which makes it the better deal even when the sticker price is higher. Get that comparison in writing so you can explain it to guests.

6. Cancellation: the penalty that scales with your guest list

Plans change. Venues fall through, dates move, and occasionally a wedding is called off. If you have to cancel the block entirely, be ready: canceling can trigger a penalty of 50-100% of the estimated room revenue.

Estimated room revenue means all the rooms, all the nights, at the contracted rate. On that 30-room, two-night block at $189, the estimated revenue is over $11,000. A 50% cancellation penalty is more than $5,500 for rooms nobody will ever use. A 100% penalty is the whole amount.

The penalty usually shrinks the further out you cancel, so the contract should include a sliding scale. Ask for the dates. A fair structure charges less if you cancel 90+ days out and more as you approach the cutoff. If the contract lists a flat 100% penalty regardless of timing, that's a clause to push back on hard.

red flags to watch for before you sign

Run the contract past this list. Any of these deserves a conversation with the sales rep before your signature goes anywhere:

Pickup set above 90%. Anything requiring near-perfect booking puts almost all the risk on you.
Attrition charged at rack rate, not the group rate. You'll pay far more per empty room.
No resale credit. The hotel keeps your attrition fee and resells the room, collecting twice.
A flat cancellation penalty with no sliding scale. Fair contracts reduce the penalty the earlier you cancel.
Comp rooms mentioned only verbally. If it's not in writing, it doesn't exist.
A cutoff date that's vague or missing. You need an exact date to plan around and to communicate to guests.
No rate-parity language. Your guests could pay more than the public price.

If a rep waves off any of these with "don't worry, that basically never happens," ask them to put "basically never" in writing. The clauses that never get enforced are the easiest ones for a hotel to remove.

before you sit down with a hotel sales rep

A room block can absolutely be worth it. Guests love the convenience, a shuttle gets easier to coordinate, and the comp rooms are a real perk. The trouble only starts when you sign commitments you didn't read. Line the numbers up before you agree to anything.

Block conservatively. Empty rooms cost you, extra rooms don't.
Confirm the exact minimum pickup percentage and do the worst-case math.
Find out whether attrition is charged at the group rate or full rate, and whether resold rooms credit you back.
Get the cutoff date in writing and put it everywhere your guests will see it.
Negotiate comp rooms in writing, at a defined ratio.
Ask for a rate-parity clause so guests never pay more than the public price.
Get the cancellation penalty as a sliding scale, not a flat number.
