Frequently asked questions
You can often adjust a room block after booking, but the process hinges on your block type and deadlines in the agreement. Courtesy blocks let the hotel release unused rooms at the cutoff; contracted blocks carry attrition terms and sometimes deposits. Ask early if you need more rooms; availability can shift fast. Hotels usually need at least nine rooms, and couples typically reserve 10-20% fewer than their guest count. Reductions after the cutoff may incur fees, while increases are added only if the hotel still has space.
A guaranteed block (contracted) in O'Fallon means you commit to a set number of rooms and timelines, often with deposit and attrition; a non-guaranteed block (courtesy) holds rooms until a cutoff with no financial obligation if they go unsold.

A guaranteed room block is a contract where you're responsible for some or all of the rooms you reserve; a non-guaranteed block is a courtesy hold with a release date and no liability for unsold rooms. Guaranteed blocks may require a deposit, set a pickup target, and include attrition fees if you drop below it. Courtesy blocks are flexible but rooms return to the hotel at the cutoff. Ask what concessions each option includes, like suite upgrades, welcome bag delivery, or extended check-out.
