South Seas was almost totally rebuilt after one of our recent hurricanes and it's now open for business again. We used to cruise our boat there from our home base on Marco Island and stay in their marina, a great location and excellent destination. Several good restaurants, tennis, biking, water activities, pools, boutiques, a very pleasant beachfront, organized activities for kids and/or adults, or you can just sit around and get fatter. They have lots of condos to rent (or own - be careful!). I don't think it has any facilities for RVs, BTW.
It's a little isolated, i.e. once you're there you won't be going to many places nearby but it has everything most people need.
Give it a try then let us all know how you like it.
