It looks like everyone here that's commented have all answered your questions. I'll ad that I really believe that whether you have a "mess" on your hands, arrival or departure, depends on the day and the circumstances. We were there a couple of weeks ago, departing on a Friday and it was 20 minutes from parking the car in the lot til the time we were in the food court having a Johnny Burger. Others in our group who left on different days, were not so lucky. This was my 3rd trip since the tents and all of them were non events, sometimes even easier before Irma.
