We are unsure when we will be arriving at the fort...could be as early as 10:00pm or as late as 1 am. We do not have reservations until the next day. Depending on the arrival time should we try to check-in early to a site (yes, we will pay the additional night) or would it be better to park in the overflow parking until morning and then check in as planned? I am not sure how late you can get into a site without disturbing everyone! In addition, Do they let you park in the overflow parking overnight? Any thoughts would be appreciated!
