I called - the phone number on Campendium and the Casino website are incorrect - so here is the phone that works: 228-392-1889 - we plan to stay Jan 2/22 and were told this is no problem.
It is a very large parking lot, so no reservations needed. Just park out and away that you don't block any of their bus parking and you will be fine. We enjoyed our time there and no one ever bothered us, but we did eat inside many times. Hope you go and enjoy this Resort.
This is not a conventional RV Park or Campground. As others have said, these are literally just regular parking lots. But they are huge and empty, so you can park just about anywhere. There are no hookups of any kind. This is dry camping.
You don’t have to reserve- just show up. It’s a huge parking lot and you will see other RVs. I called the casino and talked to security but they assured me there would be room and they were correct. It’s well lit and the security patrols the lot.
