WARNING - One or more companies are telephoning exhibitors and attendees 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. Hotel arrangements can be made immediately by clicking on the Sheraton link to the right.


All scientific sessions, exhibit show, posters and sleeping rooms will be at the Sheraton Philadelphia Downtown, 201 17th Street. The Sheraton is pleased to offer all ACA hotel guests FREE in-room internet.


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. 


Our blocks of rooms will be held until June 30, at which time the unused portion of room block will be released for general sale. The Sheraton will continue to accept reservations after this date depending upon availability and rate.

Rates are $160 per single or double room, per night, plus taxes. Rooms for students or postdocs are $119 per single or double room, per night, plus taxes. Upgrade to a Club Level room for $180 per night (upgrade not available to student/postdoc room rate), plus taxes and receive the following amenities:

  • Entry to Sheraton Club

  • Complimentary breakfast

  • Afternoon hors d'oeuvres and a variety of beverage options

  • Complimentary wireless internet access

  • Copier, fax and printer

  • Luxurious seating area and televisions

Call the hotel directly at 888-627-8178 to reserve a Club Level room. Our block of rooms begins July 23 and end after July 30. Contact <[email protected]> to book a room before or after those dates.


Room Sharing

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. If you wish to be listed as wanting to share a room, please send an email containing your name, institute, email address and gender. Once you have found a roommate, please contact us again to let us know, and we will remove your name from the listing.
