Correct. No reservations. That's why I asked what day you were coming through. If during the week you'd have no issues getting in (especially with school started). If on Friday or Saturday you might have issues but you might not. I also heard that Wilson Island might be open now but I have not been able to confirm it yet. Anyway, sounds like you got it all figured out so happy camping and be sure to wave as you come through!
