Reservations

A room block is reserved for symposium delegates at the special group rate of $209 USD for a *single or double room (plus 15% occupancy tax). The deadline to reserve your accommodations is Friday, March 14, 2025. The room block will most likely be filled before the deadline; we recommend that attendees book their hotel accommodations well before the deadline to secure this rate. The Gaithersburg Marriott requires a deposit of one night's rate plus tax via credit card to guarantee your reservation. In the event of a cancellation, the hotel requires 72 hours notice to receive a full refund.

By staying at the host hotel, you help CASSS meet its contractual obligations and keep future registration fees reasonable. Please take this into consideration when making your accommodation decisions.

*Room types are not guaranteed and are based on availability when the individual reservation is made.

CASSS is committed to protecting its attendees, participants, and staff members to the highest degree possible when attending our conferences. To ensure we provide a safe environment, CASSS strongly encourages COVID-19 vaccinations, and all other routine vaccinations to protect you from infectious diseases, serious illness, and hospitalization. CASSS will follow guidances established by the facility hosting the conference and/or local and state health authorities in which the conference is located.

For the safety of all attendees, we expect everyone to take everyday preventive actions prior to, and during the conference, to stay safe and healthy. These actions include, but are not limited to:

• Avoid close contact with people who are sick.
• If you are sick, limit contact with others as much as possible to keep from infecting them.
• Cover your nose and mouth with a tissue when you cough or sneeze.
• Wash your hands often.

Wearing a face mask throughout hotel common space and conference designated areas is recommended but not required.

If you tested positive for COVID-19, have been directly exposed to the virus, or exhibit any symptoms of the COVID-19 virus, you should isolate and not attend the in-person conference.

CASSS will follow local guidelines, including the current measures from the Montgomery County: https://www.gaithersburgmd.gov/about-us/city-news/novel-coronavirus-information
