Are sleeping rooms being offered at the Bethesda North Marriott for the Symposium?

OHDSI is holding a sleeping room block for the nights of Oct. 13 and 14 with a special room rate of $179 plus taxes. Please note that all sleeping rooms are on a first-come, first-served basis. To help us in the planning process, we ask that you do not cancel your hotel room ordered through the OHDSI Room Block. If you must cancel, please let us know prior to Thursday, Sept. 1, so that we can offer the room to others who may need one. Once the room block is full, or if specific nights are sold out, you may make additional room reservations on the hotel’s website or by calling hotel reservations. Please note that OHDSI is not holding any sleeping rooms on Saturday, Oct. 15. Therefore, please call the hotel reservations number or make this reservation on the hotel’s website should you plan to stay Saturday night.

Note: If you plan to stay both Oct. 13 and 14, and you find the night of Oct. 14 sold out on the OHDSI room block, please still make your reservation for Oct. 13 through the OHDSI room block and make the additional night by calling the hotel or going through the hotel’s website. Should you put in any other dates on the OHDSI room block, you will get a note saying that rooms are unavailable as the room block does not include pre and post room-night stays; therefore, please adjust the nights in your search to just the room block dates which are Oct. 13 and 14 only. 

Note: If you have multiple reservations at the Bethesda North Marriott, as long as you book the same room type, you will be able to stay in one room the entire time; just stop by the front desk and they will update your keys and credit card info.
