The Hyatt Regency Austin is set on the shore of Lady Bird Lake. Catch the display at the famous "Bat Bridge", right outside the hotel in downtown Austin. Wander across Congress to find yourself immersed in the entertainment districts – including SoCo, Warehouse District, 2nd Street and Sixth Street. Take full advantage of the hotel’s lake locale with a ride around the trail, paddle a canoe, relax by the pool or workout in the 24-hour gym. Critically acclaimed dining, redesigned guestrooms, elegant event venues, and the best view of downtown add the finishing touches to the inviting downtown Austin, Texas hotel.

Your support in staying at the Hyatt Regency Austin 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.


SIAM is holding a block of rooms at the Hyatt Regency Austin. 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 – Monday, May 10, 2010 (or until the room block is filled)

Single/Double       $149.00 per night plus 15% tax
Student rate         $127.00 per night plus 15% tax
(Student ID must be presented upon check-in. SIAM is able to negotiate a limited number of special student rate rooms. Please book early as these rooms sell out quickly!)

All rooms based on availability.
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.
