Government employees will be required to present ID upon check-in to receive the appropriate rate.

*Student ID must be presented upon check-in. SIAM has negotiated a limited number of reduced rate rooms for students. Please book early as these rooms sell out quickly!

Housing Scam Alert

SIAM does not share or distribute personal, registration or housing details with any company or person. Third-party solicitation of hotel reservations is not approved by SIAM, and any claim SIAM has provided attendee contact information for solicitation is fraudulent. Reservations offered by unaffiliated organizations may promise lower rates; however, they may be illegitimate, nonexistent, non-refundable, or have unreasonable cancellation or change penalties. If you book your hotel with a third-party provider, SIAM cannot assist you with any problems incurred as a result of booking outside the official SIAM room block. Please be aware of any unauthorized solicitations and report them to meetings@siam.org.

Additional Information

Did you know?

Your support in staying at the Hilton Portland Downtown 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. Currently, 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 daily, along with a hefty penalty. Future registration fees could increase to cover these additional risks.

Reservations

SIAM is holding a block of rooms at the Hilton Portland Downtown. 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 5:00 p.m. Pacific time. on May 13, 2024 or until the room block is full. If rooms are available after the cutoff date, they will be offered at the best available rate.

Room rates include complimentary internet access.
All rooms based on availability.
All rates are subject to state and local occupancy taxes.
*Additional fees of $10 per person apply to triple and quad occupancy.

In the event that you find a lower room rate, please make the reservation at the lower rate and notify SIAM immediately (meetings@siam.org). 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).

To receive the SIAM rate, make your reservations using the appropriate online reservation link or by calling the hotel directly and identifying yourself as a SIAM attendee:
Toll Free Reservations (U.S. and Canada): 800-774-1500
Direct Telephone Number: +1-503-226-1611

Do not make your reservation online using the hotel’s general website, as this will not allow you to obtain the SIAM group rate. Be sure to use the online reservation link above if making reservations online. Remember to get your confirmation number!

Reservations are not confirmed until acknowledged in writing by the hotel or verified by phone. Be sure to get a confirmation number from the hotel and be prepared to provide that number to the front desk clerk upon check-in at the hotel.

Cancellations

If you need to change or cancel your reservation, you must contact the hotel prior to 6:00 p.m. on the scheduled arrival date to avoid a cancellation fee. You can contact the hotel at 800-774-1500 (U.S. and Canada) or +1-503-226-1611. Remember to get a cancellation number!

Check-In and Check-Out

Check-in time is 3:00 p.m. and check-out time is 12:00 p.m. Pacific time.

Early Departure

The hotel may charge an early departure fee if an attendee checks out prior to the original checkout date. Attendees are responsible for informing the hotel of reservation changes as soon as possible and should confirm their scheduled departure date when checking into the hotel.

Deposit

The hotel requires a credit card to confirm and guarantee your reservation, and will send out e-mail confirmations upon request.
