Hi! Though neither of these parks are close to Disney, I can report on two of them.
Stayed at Sanlan in January 2006 so the info may be a bit dated: It was a nice enough facility. Comfort station was clean. Nothing special but clean, comfortable, and safe. 3 1/2 stars out of 5 would be my rating.
Stayed at Cypress Gardens (before it was called that) from Feb-June 2008. It was ok. Seemed to be set up for snowbirds mostly, though it did have a lot of (non-snowbird) people who lived there full-time. It had a small pool, but they closed it up daily at about 5 p.m. No playground or anything else for the young'uns. It did have a back entrance to Wal-Mart--a walking or biking gate. Several comfort stations, clean and usually plenty of hot water. A few times they were out of propane and you might have to try another station. The owners just didn't seem very friendly, and I always got the feeling they were just hanging on hoping to be bought out. Maybe 2 1/2 stars. Maybe things have changed.
Hope this helps!
