Sorry I could not be more help. Oleno was definitely nice, though. If your travels take you further south, we have camped at some other state parks such as Myakka River SP. If you can go towards Tampa/St. Pete, one of the best areas is Fort Desoto - a county park. If you head west on the panhandle, check out Grayton SP - right on/near the beach and gorgeous.
When you cross the border into Florida, stop at the first rest area and they should have a guide for the state parks. We have yet to go to a Florida state park we didn't like!
