On or before Monday, December 30, 2013, you must submit your cancellation or change online or in writing to the APTA Housing Center. Online requests will receive an immediate email confirmation. A confirmation will be sent within five (5) business days after receipt of your written request. If you do not receive this confirmation, please contact the APTA Housing Center to verify that your change or cancellation was received. Changes and cancellations cannot be made between Tuesday, December 31, 2013 and Sunday, January 5, 2014, due to the transition of the room block from APTA to the hotel. Beginning Monday, January 6, 2014, you must call your hotel directly about a change or cancellation. If you do not cancel at least 72 hours before your scheduled arrival date, your credit card will be charged a cancellation fee equivalent to one night's room rate and tax.
