We had premium reservations last week. We were there bright and early on Sunday morning. They had us registered under a preferred site. Fortunately I had my reservation slip--they weren't going to change. Finally--they put us in loop 500 which I had requested but sent us to the holding area along with many many others. 2 1/2 hours later after many many calls they let us go in. Interestingly enough we were in 556 which is the last spot. At 10 am we took the bus down to the loop to check things out and it was already empty. What a way to start the trip The loop eventually filled up but not until way after the 1 pm check in time. Several others said they had to wait also--even though the sites were already empty Hope others trips start better. The holidy spirit was not shining while we were there.
