Sham Housing Warning 

Sham housing companies are approaching 2025 Scientific Sessions attendees with fraudulent offerings of hotel rooms at significant discounts. Lured by highly attractive rates, attendees fall prey to these impostors and end up losing significant deposits, discovering hidden costs, having to pay upfront charges, or being bait and switched to hotel rooms they never booked. These "housing" companies are in no way affiliated with SCAI or the Marriott Marquis Washington, DC.  

SCAI or the Marriott Marquis Washington, DC will not contact you directly to make a reservation. The only way to guarantee a room reservation is to use the hotel booking link provided to you in your registration confirmation email.  

If you are contacted by anyone asking if you need a room reservation for 2025 Scientific Sessions or claiming to represent the “SCAI housing provider,” please get as much information as you can, then contact Jamie Parreco at SCAI via email at meetings@scai.org or call toll-free at 800-992-7224.
