Accommodations

If you change your mind later, both hotels have flexible, no-penalty cancellation policies. Review hotel details and policies when you book.
If you book after the cut-off dates listed, the discounted rate will not apply.

Stony Brook University Housing
One hundred Stony Brook University dorm rooms will be available. Dorm rooms are available starting the night of July 25, 2023 to the night of July 29, 2023. They are $80 USD/ room/ night, and a 7-minute walk to the conference venue. During the registration process, you can book a dorm room for any number of consecutive nights.
The deadline to book a dorm room is July 4, 2023. If you book a room and change your mind, please notify us by July 7, 2023. If you cancel after this date, we may have to charge you the full amount as IACFS/ME will be charged for cancelled reservations.
To see the rooms, click here and scroll down to "Lauterbur and Yang Halls." Each room is meant for 1-2 persons (2 twin beds) and 3-4 rooms will share a bathroom/ living room. However, university housing does not allow non-conference attendees (e.g. family members) to stay and cannot house people under 18 years of age. Mixing of genders within rooms or suites is not permitted (i.e., if you will be choose to share your a room, your roommate must be the same gender).
Currently, dorms stays do not require evidence of vaccination, testing pre-stay, or masks although we encourage our conference attendees to wear masks as they need. If a person tests positive for COVID-19, university policy requires that that the person isolate within their room for the majority of the time.
The main check-in time for the rooms will be on July 26 from 3 to 5 PM and then from 8 to 9 PM. If you need a check-in date/ time outside of these dates/ hours, please notify us at iacfsmeorg@gmail.com so we can make arrangements. Also, notify us if you need a handicap-accessible room.
Other Lodging
See Hotels.com, Airbnb, VRBO, house-swapping, and similar websites. These sites give you an idea of choices and prices. For the best hotel prices, try contacting hotels directly. Hotels with local shuttle services are helpful if you will not be driving.
Hotel rooms, vacation homes, and dorm rooms can be shared and the costs split. If you choose to do this, it is up to you to arrange for a roommate, assure the place you are staying allows a roommate, and split the costs with them.
Virtual Attendance
IACFS/ME plans to record all of the main Conference proceedings and portions of the Workshops. In-person interactive portions of Workshops may not be recorded due to technological challenges. Video recordings will be made available online about 2-3 weeks AFTER the Conference. In-person attendees will receive online access to the recordings for 30 days as part of their registration fee. People who cannot attend in-person can purchase video recording access. Please note that CME credits are available only for live, in-person attendance.
