# Hotel Attrition Clause Wedding: What Every Couple Should Know

> An attrition clause is the clause in your hotel room block contract that can cost you hundreds — or thousands — if your guests do not book. Here is exactly how it works, how to negotiate it down, and when to avoid it entirely.

In short
A hotel attrition clause requires you to pay for rooms your guests did not book — typically **70 to 80 percent** of your contracted block. The solution is to start with a courtesy block (zero financial risk), negotiate the attrition floor before signing any contracted block, and always require a resale and mitigation clause that protects you if guests do not fill the block.

Room blocks are one of the most thoughtful hospitality gestures a couple can offer their guests: pre-negotiated rates at convenient hotels, confirmed availability, and the irreplaceable social energy of guests staying in the same building. But for many couples, the contractual fine print arrives as a surprise — and an expensive one.

The attrition clause is the mechanism by which hotels protect themselves when couples contract more rooms than their guests ultimately book. Understanding it before you sign — and negotiating its terms deliberately — is the difference between a hospitality investment that serves your guests and a financial liability that follows your wedding home.

The guidance throughout this article is drawn from [The Knot's wedding hotel room block guidance](https://www.theknot.com/content/wedding-hotel-room-block), reported practices from hotel group sales professionals, and current standard hotel contract terms across major chains including Marriott, Hilton, Hyatt, and IHG properties.

## How does a hotel attrition clause actually work?

The attrition clause is a financial floor built into contracted room block agreements. When you sign a contracted block with a hotel, you are committing to fill a minimum percentage of the reserved rooms — or pay for the difference. Here is the math in concrete terms.

  Hotel attrition clause: sample calculation scenarios, 2026

      Contracted Rooms
      Attrition Floor
      Minimum Fill (rooms)
      Actual Bookings
      Rooms You Owe For
      Estimated Liability*

      Scenario A: 30 rooms, 80%
      80%
      24 rooms
      22 rooms
      2 rooms
      $636 (2 nights × $159)

      Scenario B: 30 rooms, 80%
      80%
      24 rooms
      16 rooms
      8 rooms
      $2,544 (2 nights × $159)

      Scenario C: 30 rooms, 70%
      70%
      21 rooms
      16 rooms
      5 rooms
      $1,590 (2 nights × $159)

      Scenario D: 20 rooms, 70%
      70%
      14 rooms
      12 rooms
      2 rooms
      $636 (2 nights × $159)

*Liability calculated at $159/night × 2 nights for illustration; actual rates vary. A resale clause reduces or eliminates these amounts if the hotel fills unsold rooms.

The two most important variables in this math are the attrition floor percentage and the resale clause. Negotiating the floor from 80 percent to 70 percent meaningfully reduces your exposure. A resale clause that obligates the hotel to sell unfilled rooms at the group rate before charging you can reduce your liability to zero at hotels with strong weekend occupancy — which describes most urban and resort properties on peak-season Saturday dates.

## When should you choose a courtesy block instead of a contracted block?

For the majority of couples, a courtesy block is the right choice. The financial logic is straightforward: a courtesy block requires no deposit, no signed financial commitment, and no attrition exposure. The hotel holds 10 to 20 rooms at a negotiated rate until a cutoff date, then releases unsold rooms back into inventory. If all 20 rooms fill, your guests benefited from a discounted rate at a convenient location. If only 8 fill, you owe nothing.

The trade-off is that courtesy blocks offer less certainty of availability — if the hotel's weekend fills from other sources, your courtesy block rooms may not all remain available. They also carry less negotiating leverage for perks. But for couples with fewer than 40 to 50 out-of-town guests, or couples uncertain about their out-of-town attendance rate, the financial protection of a courtesy block is almost always worth the trade-off.

Contracted blocks make sense when your out-of-town guest count is large (60 or more rooms needed), when you have high confidence in your fill rate based on a tight-knit guest community or a destination event, and when you have successfully negotiated an attrition floor of 65 to 70 percent with a strong resale clause.

## What is the complete room block timeline for a 2026 or 2027 wedding?

Room block planning is one of the most time-sensitive logistics decisions in wedding planning. Hotels — particularly sought-after properties near popular venues — begin receiving group inquiries 12 to 18 months before peak-season dates. Couples who begin their hotel outreach at 6 months find limited availability, limited negotiating power, and less favorable terms.

The recommended timeline: at 10 to 12 months before the wedding, contact the group sales department at three to five hotels with a letter or email describing your event, anticipated room count, and dates. Request a group proposal from each. At 9 to 10 months, compare proposals on rate, attrition floor, resale clause, perks, and proximity to the venue. Negotiate terms. Sign your agreements by 9 months. At 7 to 8 months, include the hotel booking link and cutoff date prominently in save-the-dates. At 45 days before the cutoff, send a direct reminder to all guests who have not yet booked. At 14 days before the cutoff, send a final reminder and flag the urgency of the deadline.

A room block managed with this timeline and these protocols will almost always fill adequately. The couples who face attrition surprises typically set a 30-day cutoff, forgot to remind guests, or contracted far more rooms than their realistic out-of-town count justified. The mechanics of a successful room block are not complicated — but they require consistent execution over a multi-month window. Assign the reminders to a trusted bridesmaid or family member if the coordination detail is not something you want to manage personally in the final weeks before your wedding.
