Do not think they rent RV units.
They have really nice cabins with or without bathrooms. They keep all the bathrooms clean, but the floors will tend to get wet as the day goes on. The campsites are great also, and they're right in the middle, so it's a close walk to the beach or the pool. If you are determined to be in an RV, I'm sure you can find a local rental in the area. Some folks are putting their RVs on VBRO now, which should be cheaper. Good luck, and have a fun trip!
You'd need to check their website. I know they have cabins, not sure about campers/RVs for rent.
