The ceiling fans really help with air circulation. However, if the sound of a fan is what you also need (and I can relate) than just take your own. I have a small box fan that has always fit nicely in my suitcase. As the other poster said, they don't have them for loan or rent at this resort.
Also, if you have a car, you can stop and buy one at Wal Mart and then just leave it there when you check out.
