We have been to FW many times - probably a dozen. If you did on-line check in, all your paper work is completed. You stay in your vehicle in special drive through lanes. The Cast Member will give you your packet and directions to the campsite. Even when there is a line, it goes pretty quickly. I think the busiest time is 2-4pm as campsites are generally available before then. When we have arrived earlier, we have once received our site and another time we had a short wait. Frankly, I wouldn't try to go early morning.
