Can you switch campsights when you arrive if you already have reservations?

You can switch to a first come first serve site if its available but you would have to pay the site fee again I believe and no refund on your reservation

Here it is in detail...If the campground isn't busy, pre July or after Labor Day, the hosts probably won't mind, but ask first...but if you do move, don't move your reservation placard from the post as someone will think it's a first come first serve site. If you cancel your reservation and pay at the campground, you can move to any available site that you want, but it'll cost you a cancellation fee of $10.
