Warning: 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 hotel themselves. No hotel will call you to make reservations. Hotel arrangements can be made immediately by clicking on the link on this page. 

It has been brought to our attention that an unauthorized company called Ehotel Services is contacting our ACA 2020 participants trying to get them review and sign an online booking form and to make payment for accommodation for ACA 2020. PLEASE NOTE that Ehotel Services is NOT affiliated in any way with ACA, nor have we authorized them to use our name or trademarks on email or documents that they are sending out. Please be cautious if you receive an email or phone call from them.

If you would like to book your accommodations, please use the link on the ACA meeting page and/or contact the hotel directly (+1 619-291-2900) and advise that you are attending the ACA 2020 Conference and would like to reserve a room in the ACA block.
