If your hotel reservations were made through the official housing bureau, Orchid Event Solutions, your reservation will automatically be canceled with no penalty.
If you booked directly with a hotel that was inside the ACSM housing block, you should be able to cancel at no charge as well; however, you will need to cancel the reservation yourself (the hotel will not automatically cancel it).
If you reserved a room at a hotel outside of the ACSM block, you need to cancel that reservation yourself.
