Try to get the curve of the loop. It let's you pull up the loop past your spot and back almost straight back in.
The sites on the curve of sea urchin loop are pretty big and seem easier to back into than the ones on each sides. I don't recall the exact numbers though but you can see them on the campground map. I was in site #75 and it was very tight for just my truck and 18' tt.
Alligator park was cool. Loved the feeding show. Tried going through trails at park but mosquitoes were bad and tore us up.
