Why Choose an Official AAAR Hotel?

All AAAR attendees and exhibitors are encouraged to make hotel reservations by utilizing the official AAAR hotels.

The association recognizes that attendees have many options with other area hotels and that you may be looking only at the per-night cost in making your decision. However, we encourage you to take a few minutes to understand the importance of selecting the official AAAR hotels and other factors which go far beyond the per-night rate.

AAAR has a long history of consistently fulfilling the minimum number of room nights to be sold according to the association’s contracts with hotels. However, with the current economic climate and competition from other properties, it gets more difficult each year to ensure that the number of guaranteed contracted sleeping rooms will be used by attendees and exhibitors.


What Does This Mean to You?

When AAAR is able to maintain a consistent history of hotel rooms sold, it helps the association negotiate the lowest hotel rates possible for future AAAR conferences.

AAAR earns credit for each room night utilized by an attendee or exhibitor when the reservation is at an official conference hotel. This credit helps to offset meeting room rental costs, therefore keeping conference fees low.

The AAAR hotel contract protects YOU. Booking within the AAAR hotel block gives AAAR the opportunity, if the need does arise, to assist you with potential hotel problems you may experience while at the conference. When you choose other hotels, AAAR staff has no contacts or leverage to help rectify a problem or inconvenience which you may have encountered.


IAC 2018 Registrants, Exhibitors and Sponsors: Beware of Hotel Piracy

We have been advised that a company called Elegant Housing LLC is soliciting AAAR members and exhibitors and offering discounted hotel rates at various venues in St. Louis for the upcoming International Aerosol Conference (IAC). 

Please be aware that this company IS NOT AUTHORIZED by the AAAR to solicit our members or exhibitors and that the AAAR has no knowledge of this company or its legitimacy.  

Hotel piracy is rampant in the convention industry.  Beware of fraudulent phone calls, emails and websites offering services linked to the IAC and/or the AAAR. These companies are not linked to the IAC or the AAAR and are using our name without authorization.  If you make a reservation with one of these companies, you may or may not end up with a room, and you will likely never see your money again.  The safe way to make your hotel room reservation is to click on the link provided on the IAC 2018 website –

The AAAR will send marketing emails reminding you to make your reservation, especially as we near the cut-off date. These emails will always link directly to the IAC 2018 website.
