Group Reservations
Groups in need of 10+ rooms are required to complete the group reservation request form, found via the button above. Hotel assignments will be based on the date the form is submitted, hotel availability, block size, meeting space needs, and exhibitor's priority preference. Any exhibitor circumventing the ACS housing system will be assessed 10 penalty points.

The total room nights requested on your block may be reduced by 20% without penalty up until Friday, August 9, 2019. Should the actual room night’s utilized drop below 80% of the total room nights held after this date, your company agrees to pay the room rate plus applicable taxes for each room night that is not used by your company in excess of the allowable slippage. If payment is due under this provision due to actualized slippage, an invoice will be sent to your company, and payment will be required no later than 30 days after receipt of invoice.
