Do not be misled by outside housing or travel agencies claiming to be the official housing provider for the upcoming AHA annual meeting. Only AHA’s official housing service, Maritz, can book rooms at the AHA’s discounted rate. Unfortunately, unscrupulous providers sometimes claim to provide housing for meetings and conventions when they are in no way affiliated with the sponsoring organization. This practice is a scam that attendees should be aware of in order to avoid passing on personal or financial information. Reservations made by unaffiliated organizations may be illegitimate, not have the rooms to sell, have unreasonable cancelation or change penalties, or be completely non-refundable. Please notify us at annualmeeting@historians.org if you are contacted by any company claiming to provide housing for the AHA.

ADA Access

Attendees requiring ADA accommodations should contact Maritz by phone or by email at AHA@maritz.com. The customer service team at Maritz will contact the hotel to determine availability of specific accommodations and contact you with a final confirmation. See our accessibility page for information about ADA access at each property.


Suites range from $179 to $3,000 per night. These suites can be booked through the housing site. E-mail AHA@maritz.com for the most up-to-date information on on suite availability and details about the layout and furnishings. Please note that for suite reservations, the customer service team at Maritz will take your information and contact the hotel to confirm the availability of the type of suite you have requested. This process can take some time, so you will not receive an immediate confirmation of your reservation. Maritz will contact you as soon as they obtain a final confirmation.

Note that use of suites is subject to the AHA Code of Professional Conduct, and activities in suites are not considered part of the official meeting program. 


Maritz will acknowledge reservations via email. All processing deadlines and cancellation policies are noted on acknowledgements. A reservation ID number will be provided on the acknowledgement. You will not receive a separate confirmation from the hotel. Please note that prior to December 19 you should call Maritz rather than the hotel to confirm or alter your reservation.

Cutoff Date

The last day to make or change reservation through the housing service is Wednesday, December 13, 2023. After that date, remaining inventory in each hotel's block will be released and rooms will be available at the AHA's convention rates on a space-available basis. If hotel blocks sell out, the AHA will secure additional hotel rooms and post details on the AHA website.

After December 19, 2023, all reservations, changes, and cancellations must be made directly with the hotels.

Credit Card Guarantee

All reservations must be guaranteed with a major credit card valid through February 2024. The credit card used to guarantee your reservation may be charged a one night’s room and tax deposit by the hotel on or after December 14, 2023.


Meeting attendees can make and modify (depending on availability) reservations with Maritz via the website, phone, or email through 5 p.m. ET on December 22, 2023.

No changes or new reservations can be made between December 13 and December 19. After December 19, all changes and new reservations must be made directly with the hotels.


Cancellations must be made 72 hours prior to the scheduled arrival date or hotels will charge a cancellation fee of one night’s room and tax.

Early Departure Fee

Guests wishing to avoid an early departure fee should advise the hotel at or before check-in of any change in planned length of stay.

Third-Party Billing

If a third party such as your employer will pay for your hotel room and you will not have a credit card with you at check in, contact the housing bureau to arrange billing.

You can also reach out to the hotel to request a credit card authorization form.


Please be aware that some hotels place a $75 per night temporary hold on your credit card when you check in to cover potential incidental charges such as room service and meals charged to your room. This hold is released when you check out.

Tip Your Housekeeper!

Hotel housekeepers count on tips as part of their overall earnings. Leave a tip at the end of your stay for the person who will clean your room after you check out. If you have daily housekeeping, leave a tip every day as your housekeeper may change.
