Deceptive tactics by housing "pirates" may include:
• Informing attendees and exhibitors that the GTH 2018 hotel room block is sold-out and that if you do not book with them immediately, you may not get a room
• Distributing forms or promotional materials that appear to be issued by GTH
• Non-delivery of promises to customers; when customers arrive, reservations are sometimes non-existent or the hotels are not conveniently located
• Illegally using GTH's name and/or logo to falsely represent themselves as being affiliated with GTH
