Did you know?

Your support in staying at the Westin Peachtree Plaza 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 Westin Peachtree Plaza. 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 PM 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.
