Hotel Room Blocks for Wedding Guests: How They Work
How hotel room blocks work for weddings, when to book one, how many rooms to hold, what attrition and cutoff dates mean and how to share booking details.

Room blocks protect your guests from sold-out hotels and can make travel easier. They can also create risk for you if the contract requires you to pay for unused rooms. Understanding the terms before you sign is the key. With a little planning, a block can be a simple gift to your guests.

How room blocks work
You contact one or more hotels, share your dates and expected room count and ask for a group rate. The hotel holds a set of rooms and gives you a booking code or link. Guests book directly with the hotel at the group rate, usually until a cutoff date. After the cutoff, unbooked rooms return to general sale and the rate may change.
There are two main types. A courtesy block holds rooms without a financial commitment, usually with a cutoff. A contracted block may include an attrition clause, which means you may owe money if guests book fewer rooms than a set percentage. Ask which kind the hotel offers, and ask to see the contract.
How many rooms to hold
Start with your out-of-town guest list. Count households, not people, because couples and families usually share rooms. Then estimate how many will stay at the hotel instead of with family or in other lodging. Many couples hold around 70 to 80 percent of the rooms they expect guests to need, which keeps risk low and still gives guests options. If the wedding is in a popular weekend, hold more. See how to cut a wedding guest list if your count is still changing.
Consider holding blocks at two price levels or two hotels, so guests with different budgets have options.
Questions to ask the hotel
Ask about the group rate and how it compares with the public rate. Ask about the cutoff date, cancellation rules for guests and for you, attrition, parking fees, breakfast, shuttles and whether you can add rooms later. Ask what happens if the hotel sells out before the cutoff. Ask if there is a complimentary room for the couple or a discount on a suite. Get everything in writing.
Sharing the block with guests
Put the hotel name, rate, booking code, cutoff date and a link on your wedding website and on your save the date or invitation. Remind guests as the cutoff nears. Explain that booking early is wise, and that guests can still choose different lodging. Do not make guests feel obligated to stay in the block.

Alternatives to a room block
A formal block is not always necessary. For a small wedding, you can simply share two or three hotel options at different prices, with a note about booking early. For a larger wedding, a block gives guests a rate and a simple way to find each other. Some couples use rental apartments or houses for family groups, which can be cheaper per person but need coordination.
If you skip the block, tell guests which hotels are near the venue, how long the drive or ride is and when to book. Peak weekends can sell out, so mention that early. A short list of options, with links and rough price levels, helps guests make decisions without obligating you to any contract.
Chicago-area notes
In Chicago, hotels near downtown fill quickly on weekends with conventions, sports and festivals, so book blocks early. Downtown rates may include higher taxes and parking costs, while suburban hotels often have lower rates and free parking. If your venue is far from the city, ask hotels about shuttles. For winter weddings, consider adding a few extra rooms in case weather delays travel. If your guests are arriving at O'Hare or Midway, tell them about transit and rideshares. Ask hotels about late checkout on the day after the wedding for your guests. Keep a copy of the block contract and the hotel's contact person in your planning folder, and check the pickup report with the hotel a few weeks before the cutoff. If bookings are slow, a personal reminder to guests often moves the number more than another website update.
