I may not be there anymore?? There's Highland Park Fish camp but they don't have block rooms & aren't on a lake but are near Lake Woodruff Wildlife Refuge.

There's Riviera Resort/Marina in Deland, its pretty much on the river but near Hontoon Island State Park & Lake Beresford.

There are several in Astor just south of Lake George - Southmoon, Parramores & Blair's Jungle Den
