We are able to offer the special discounted room rates due to a commitment to contract for a minimum number of sleeping rooms at this hotel. If we do not fill these blocks, financial penalties will be incurred. This ultimately impacts the health of the ACA. Staying at the conference hotel also helps keep future registration fees lower. 


A special room rate has been negotiated for students and postdocs only. You must register as a student or postdoc meeting participant to be allowed to reserve a student/postdoc hotel room. 


Rates are $165 for one person, $190 for two people, $215 for three people, $240 for four people. Prices listed are per night and plus taxes. Rooms for students or postdocs are $139 per room, per night, plus taxes.These discounted rooms are ONLY for students and postdocs. If you make a reservation at this rate but are found to be ineligible, you will be asked to cancel and rebook at the appropriate rate. New reservations will be subject to hotel's availability.

Room sharing is an option for those looking to save money on their hotel accommodations.This service is strictly for facilitating contact between roommates and does not guarantee availability. Once contact is made, attendees will still need to reserve a room directly with the hotel.

Once you have found a roommate, please contact us again to let us know, and we will remove your name from the listing.

One or more companies may telephone you claiming to be hotel room agents for the ACA Annual Meeting. These companies are not legitimate room booking agents for us. ACA does not use booking agents. We strongly recommend that you make hotel arrangements early. Some scammers even pretend to call from the Hyatt itself. The Hyatt will NOT call you to make reservations. Hotel arrangements can be made immediately by clicking on the links above. 




Use this link for reservations. Please remember that if only one of your dates is unavailable at the hotel, the online system will deny your reservation. If in doubt, call the hotel at (504) 561-1234 and be sure to identify yourself as an ACA Meeting Attendee.
