I did see 2 girls, one about 12 and the other about 2 years old. But only saw each of them one time in the week we stayed there. They were with their parents, and everyone was behaving as though it was normal. Nothing sexual by any means.

Yes, but just ok. There are a lot of restaurants nearby.

Call in the afternoon to let them know you're on your way first, and you shouldn't have any problems. As for towels, the unit we stayed in had bath towels but no beach towels. There are beach towels for sale at the front office.

For the lake, paddle boats and small sail boats are available. Given the possibility of alligators in the water, (this is Florida after all) swimming and using personal floaties isn't encouraged. As for the pool, there is a large barrel full of foam pool noodles for anyone to use, and guests are welcome to bring their own noodles and personal floaties providing they aren't so large as to affect other people's use of the pool.
