I've never done the CP package before. I have a reservation at 340. There is a show at 5, 645, and 815. Can I go to any of these, or does my dining time dictate which show I'll be let into? How early is it necessary to line up ahead of time with the package?
Your time will be assigned to you. A reservation at 3:40 should mean you are attending the 6:45 show, based on last years times.
You will still want to expect to line up about 30 minutes in advance. The line will still be quite long, though all packages will be allowed in before the standby guests.
