I believe when you rent from Fort Wilderness, ( bike barn) that your credit card has a hold on a one-day deposit, then the day before you arrive, your credit card is charged the entire amount. Somebody else may chime in here with a bit of additional information. A couple of years ago, we had to leave the Fort a day earlier, and we returned it by 11:00 am the early departure day, and we were refunded the additional day. Have a fabulous trip.
