How to Reserve a Room

The importance of reserving a hotel room at one of the official Joint Mathematics Meetings (JMM) hotels cannot be stressed enough. The AMS and the MAA make every effort to keep participants’ expenses at the meeting, registration fees, and hotel rooms for the meeting as low as possible. They work hard to negotiate the most affordable hotel rates and to maximize the best use of your registration dollars. The AMS and MAA encourage all participants to register for the meeting. When anyone pays the registration fee and reserves a room with an official JMM hotel, he or she is helping to support not only the 2020 JMM, but future meetings as well.

Full List of Hotels


Participants are encouraged to register for the JMM in order to reserve hotel rooms at the contracted JMM rates. If a participant needs to reserve a hotel room before they are registered for the JMM, he or she must contact the Mathematics Meetings Services Bureau (MMSB) at mmsb@ams.org or 1-800-321-4267 ext. 4137 or ext. 4144 for further instructions.

Special rates have been negotiated exclusively for this meeting at the following hotels: Hyatt Regency at Colorado Convention Center, Embassy Suites by Hilton Denver Downtown, Hilton Denver City Center, Crowne Plaza Denver, The Curtis, Hyatt House, Hyatt Place, Homewood Suites Denver Downtown Convention Center, Hampton Inn & Suites Denver Downtown Convention Center, and Sheraton Denver Downtown Hotel.

ALERT to All Participants

Please be aware of any kind of promotion sent to you from anyone other than the Mathematics Meetings Service Bureau (MMSB). There are no other 2020 JMM websites other than this one. There is NO other company or organization authorized to reserve rooms for you, register you, sell you booth space, sell lists, or the like. And there are no promotion codes generated with special deals. All JMM rates offered at the official JMM hotels are already heavily discounted solely for this meeting. 

These groups are getting more and clever with their promotional campaigns, including using our pictures and logo, mimicking our website, and even listing themselves as representatives of the AMS and MAA; nevertheless, they are SCAMS. All correspondences from us will come from mmsb@ams.org ONLY.
