We're scheduled to arrive at FW the Sat after Thanksgiving, but I've pinned all of my hopes (and dining reservations) on the possibility that there will be an opening for that Friday and that we'll be in the parks on Saturday. As of right now they're all booked up. My question is this: If we go ahead and arrive on Friday afternoon, what are our options for boondocking down there? I've seen many campers waiting in the lot for a site to be prepared, but I'm thinking that they might frown on us waiting there for 18 hours.
