Did you know?

Your support in staying at the Boston Park Plaza Hotel & Towers 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. Future registration fees could increase to cover these additional risks.



SIAM is holding a block of rooms at the Boston Park Plaza Hotel & Towers. 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 – Thursday, April 10, 2008, 5:00PM EST (or until the room block is filled)

Single/Double       $149.00 per night plus 12.45% tax
Student Rate        $100.00 per night plus 12.45% 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.

Your reservation is not confirmed until acknowledged in writing by the hotel or verified by phone.
