JMM 2019 Baltimore

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 2019 JMM, but future meetings as well.


The deadline to reserve a hotel room through the MMSB has passed. To reserve a room for the JMM, please contact one of the JMM hotels directly after Monday, December 17, 2018, at the number provided for each hotel on the detailed hotel page. Any updated contact information will be posted on that page first. At this time, rooms and rates will be based on availability only. Any rooms reserved directly with the hotels after December 13, 2018 are subject to rates higher than the JMM rates. Please send email to if you are having trouble reserving a room, and require some assistance.

ADA Accessibility

We strive to take the appropriate steps required to ensure that no individual with a disability is excluded, denied services, segregated, or otherwise treated differently. If special assistance, auxiliary aids, or other reasonable accommodations to fully participate in this meeting is required, it should be indicated in the appropriate section on the Registration and Housing Form or emailed to the MMSB at Requests for ADA-accessible rooms should also be clearly indicated when making hotel reservations. All requests for special accommodations under the Americans with Disabilities Act of 1990 (ADA) must be made allowing enough time for evaluation and appropriate action by the AMS and MAA. Any information obtained about any disability will remain confidential.

Beware of Room Poachers, Housing Scams, and Registration Scams

Please beware of aggressive housing bureaus that target potential attendees of a meeting. They are sometimes called "room poachers" or "room-block pirates" and these companies generally position themselves as a meeting's housing bureau, convincing attendees to unknowingly book outside the official room block. They call people who they think will more likely than not attend a meeting and lure them with room rates that are significantly less than the published group rate -- for a limited time only. And people who find this offer tempting may hand over their credit card data, believing they have scored a great rate and their housing is a done deal. Unfortunately, this often turns out to be the start of a long, costly nightmare.

Note that some of these room poachers create fake websites on which they represent themselves as the organizers of the meeting and include links to book rooms, etc. The only official website for this meeting is the one you are on now and one that has the official JMM logo.

These housing bureaus are not affiliated with the Joint Mathematics Meetings in any way. The only official housing bureau for this meeting is the MMSB and they would never call anyone to solicit reservations. The only way to book a room at a negotiated JMM rate is through the JMM registration form or through the MMSB. The JMM cannot be responsible for any damages incurred as a result of hotel bookings made with unofficial housing bureaus.

The JMM only sells attendee lists to JMM Exhibitors and Sponsors, and only for a one-time promotional use. Exhibitors and Sponsors are not authorized to sell JMM lists to anyone. Nor does anyone else have the authority to sell any lists generated by the JMM. Beware of any person or group approaching you about purchasing a list generated by the JMM. It would not be an authorized representative for the JMM, under any circumstance.
