BUYER BEWARE of Possible Hotel Reservation Fraud

We have been made aware of unauthorized companies contacting ACT exhibitors and registrants offering hotel reservations at the ACT headquarters hotel. These “unofficial” housing companies are aggressively pursuing exhibitors and attendees to book hotel rooms through their company at supposedly significant discounts. Unfortunately, some past attendees have fallen prey to these companies and have been relocated with little or no warning, lost their significant deposits, not been given the type of guest rooms they thought they had booked, or not been given the hotel they thought they had booked. This has caused great hardships to these individuals.

ACT does not work with an official housing company. Please be sure to make your reservation directly with the hotel via phone or the housing links. Reservations made through anyone other than the hotel or their reservation center will be at your own risk. Please note that the Gaylord National Harbor does not solicit reservations or credit card information by phone. If another housing company trying to sell hotel rooms contacts you, please notify ACT Headquarters.
