ANS has made every effort to secure the best possible nightly room rate for you at the Chicago Marriott Downtown. That rate results from a negotiated overall package of event needs including but not limited to sleeping rooms, meeting room space and other requirements.
Please help ANS keep the costs of this event as low as possible by booking your housing needs at the host hotel and through the reservation process created by ANS. Reserving your rooms elsewhere means you are booking outside the contracted room block, jeopardizing ANS’ ability to meet its contracted obligations. Unfortunately, if this happens, event costs will continue to increase if ANS falls short of its minimum room block guarantee. ANS appreciates your support and understanding of this important issue. Thank you!
