Interesting, we seem to be taking the same path. We were in Crystal River at Rock Crusher in Feb this year (and again next Feb) and in Wauchula in Jan. Sorry, can't help you with Quail Roost. We never made it up in that direction when we were there although we drove thru a couple other campgrounds in the area. Hard to beat Rock Crusher but when we left they were down to only 76 sites left unreserved for next winter and most of those were less desirable.
