My son did the Junior High Career Camp at Sea World Orlando last summer. Two of the nights they slept at animal venues. One night they were in the Wild Artic by the Polar Bears and Beluga whales. Then they slept at the Marriott Residence Inn for a few nights. The last night they slept by the Dolphins. Mats were provided to put their sleeping bags on. I'm just guessing that you might sleep at one of these venues. If the quality of this camp is any indication of what your overnight experince will be like, you're in for a real treat.
