They usually open up the CP reservations in mid Aug. I highly recommend booking the pkg if you have the dining plan. Just a ?, have you considered eating first and doing a later show? The reason I ask this, is because it is still pretty light out at 5:00 which in my opinion takes away from the beauty of the show. Of course, this is just a suggestion, you and others may think differently. This past November, my dh and I had a 4:00 ADR at Lecellier and then saw the 6:45 (or whatever time the 2nd show starts) show. We had plenty of time to eat, and were even able to catch the tree lighting ceremony before we had to get in line. Anyway, I hope you have a wonderful time !
