Did you know?

Your support in staying at the Westin San Diego Gaslamp Quarter 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 then 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 Westin San Diego Gaslamp Quarter . 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 the cutoff date unless the block fills prior to that.  If there are rooms available after the cutoff date, they will be available at the best rate offered at that time.

Reservation Deadline: December 1, 2014 EXTENDED to 5:00 PM Pacific Time, Monday, December 8, 2014  (or until the room block is filled)

All rates are subject to state and local occupancy taxes.

In the event that you find a lower room rate, please make the reservation at the lower rate and notify SIAM immediately ([email protected]).  By doing this you will receive the lower rate and be counted towards the SIAM room block.
