Guestroom Reservations
Reservations at the Crowne Plaza Hotel can be made online here. Please note that the guestroom block expires April 14, 2025. Follow the steps to create your hotel reservations online. We do not recommend calling the hotel to make reservations. Often, you get forwarded to the central reservation line and they do not always have accurate information. However, if you must, you can call 217.529.7777 and use option #1 - Group Code: I5A. The hotel will provide you with a confirmation number. Rate: $107/per night plus tax. Self-Parking is complimentary. Hotel Cancellation/no-show policy: Reservations made and not cancelled 24 Hours prior to the 1st day of check-in will be billed for the first night’s room and tax and the remaining nights reserved will be cancelled.
We also have a small block of rooms at the Holiday Inn Express, located next door to the Crowne Plaza. Follow this link to make your Holiday Inn Express reservation.
PLEASE ONLY RESERVE THE HOTEL ROOMS NEEDED! IACO loses the room nights when reservations are cancelled after the cut-off date and this can cause us to drop below our contractual room block commitment.
IF YOU HAVE PROBLEMS MAKING A RESERVATION (or are told they’re sold out), contact Sandra Wulf at [email protected] or call the IACO office at 217-217-5998.
Conference cancellation policy: Conference registrations made and not cancelled will be billed. Cancellations must be made in writing on or by April 30 to receive a refund. All refunds (less a $25 processing fee) will be made via a check mailed to the attendee after the conference.
