Changes/Cancellation Policy

Reservations must be cancelled at least 72 hours prior to arrival to avoid loss of deposit. If you need to make any changes or cancellations to your reservation on or before September 4, 2015, make your changes through the onPeak online reservation system or call 1-800-219-8916. Changes or cancellations to your reservation after this date must be made with the hotel directly. All changes are based on availability. Failure to arrive on your confirmed date will result in one (1) night’s room and tax no-show penalty (charged to the credit card provided).

10+ Rooms: Attrition/Changes/Cancellation

Rooms without names will be released and placed in attendee general sale on July 16. All changes and cancellations must be made in writing to ASHG Housing 72 hours prior to arrival. Cancellations received less than 72 hours prior to arrival will be charged one (1) night’s room and tax cancellation fee (to the credit card provided) in addition to forfeiture of your hotel deposit. For any cancellations made at least 72 hours prior to the arrival date, the deposit will be refunded. Failure to arrive on your confirmed date will result in one (1) night’s room and tax no-show penalty (charged to the credit card provided).

Every group reserving 10 rooms or more must agree to a room block agreement contract. Once the group block is confirmed, each group will be responsible for picking up 80% of the block's total room nights. Groups will be required to confirm the total number of room nights needed as well as a list of names assigned to the block by July 15, 2015. Any rooms not confirmed by this date will be released. Should the actual block fall below 80% of the confirmed block, the group will be billed the difference between the hotel's actual pickup numbers and 80% of the agreed-upon total room nights. These monies are due within 30 days of receipt of invoice.

Bulletin Board for Room Sharing/Car Pooling

In order to save on hotel and travel costs, we encourage use of the bulletin board to find a roommate, to share a ride/car pool or just to start a discussion on a topic of interest.
