A hotel room block locks in a rate for your guests and saves you the embarrassment of having them scramble for rooms on a busy Vegas weekend. Here is how the process actually works and what to watch out for.
What a room block is and why it matters in Las Vegas
A group room block is an agreement between you and a hotel to hold a set number of rooms at a negotiated rate for your guests. Las Vegas hotels are among the most aggressively rate-managed in the world — a room that costs $120 on a Tuesday can spike to $400 on a Saturday with a boxing match in town. Locking in a rate weeks or months ahead protects your guests from that volatility.
Blocks also keep your group in one place, which simplifies transportation, reduces late arrivals and makes the day-after brunch logistically simple.
The attrition clause — read this before you sign
The most important thing to understand about room blocks is attrition. Most hotel contracts require you to fill a certain percentage of the rooms you reserved — typically 80–90% — or pay a penalty for the unsold rooms. If you block 20 rooms and only 14 guests book, you may owe the hotel for some of the remaining six.
Negotiate the attrition percentage down (aim for 70–75% or "no-attrition" blocks if you can), set a realistic block size, and build in a release date 30–45 days before the wedding. Any rooms not picked up by the release date go back to the hotel's general inventory.
How to choose the right property for your block
Match the hotel to your guest demographics and your venue location:
- Venue-attached hotels — If you are marrying at a Strip resort, negotiate the block with that property. Guests walk to the ceremony; transportation cost is zero.
- Near-venue hotels — For off-Strip venues, pick the closest well-reviewed hotel and negotiate a block there. Your guests will need one short rideshare instead of a 20-minute drive.
- Anchor + overflow — For 50+ guests, consider one primary block at a mid-range property and a second smaller block at a budget option nearby.
Negotiating the rate and perks
Groups of 10 rooms or more usually qualify for a group rate at Las Vegas properties. Typical perks to ask for: complimentary room upgrades for the couple, a suite for hair and makeup, early check-in for the wedding party, and a waived resort fee. Not every hotel will agree on every perk, but they are accustomed to these requests from wedding groups.
The group sales desk (not reservations) is who you call. Weekday weddings and off-peak months (May–August, January–February) have the most negotiating leverage.
Giving guests the booking link
Once the block is set, the hotel provides a dedicated booking link or group code. Put it on your wedding website with the rate, the cutoff date and a short note explaining why booking through the block benefits them (locked rate, close location, ease of group transportation). Remind guests in your RSVP follow-up — many people skim the first email and book elsewhere without realizing there was a block.
