Did you know?

Your support in staying at the DoubleTree by Hilton Hotel Portland helps keep the conference costs down, which directly affects your registration fees. SIAM guarantees the hotel that we will fill a certain number of “room nights” (rooms per night) during the conference. SIAM incurs penalties if too many attendees opt to stay in other hotels in the area or neglect to indicate to the hotel that they are with the SIAM conference. At this time, conference costs do not include meeting room rental. If SIAM fails to fill the contracted room block, SIAM is charged the cost for the meeting rooms on a daily basis, along with a hefty penalty. Future registration fees could increase to cover these additional risks.


SIAM is holding a block of rooms at the DoubleTree by Hilton Hotel Portland. These rooms are being held on a first-come, first-served basis at the following discounted rates. Please be aware the room block fills quickly, so we suggest you make your hotel and travel plans early.

The group rate is guaranteed until 11:59 p.m. local time on the cutoff date or until the room block is full. If rooms are available after the cutoff date, they will be offered at the best available rate.

By doing this you will receive the lower rate and be counted towards the SIAM room block. However, please be aware by booking outside the SIAM room block at a lower rate, you may not receive the same benefits as rooms reserved in the SIAM room block (i.e. complimentary internet access).

Toll Free Reservations (U.S. and Canada): 800-445-8667
