Step 2: Select a Hotel for your event. Halloween Havoc O'Fallon, IL October 28-30, 2022 Thank you for visiting GCI Team Travel. ATTN First Time GCI Customers and New Traveling Teams: The process works best when a team manager (or parent) sets up a block of rooms for their travelling team. There is no credit card required to set up a room block. Only the individual parent will provide a credit card to secure their own room within the room block. Important Dates: Hotel inventory was posted here on June 20th. Hotel inventory will be closed down for new bookings by October 11th as hotels ask for their unsold inventory back on this date. Please make your selections early to get the best pricing and selection. Thank you! Any questions? Email is the best way to reach me ~ Lori at LMurawski@exploregci.com Thank you!
