The PS is for 6:45 at Tony's Town Square on a MNSSHP that begins at 7. Would you keep it? Or is it better to just get into the parks and start the Halloween activities? Will they let you remain in the Park after you eat, or do you have to leave and re-enter again?
It was my experience last year at MVMCP that we did not have to leave and re-enter. We ate at CRT and we finished our meal just as the event was starting.
We arrived at the MK between 5:00 and 5:30, and were asked to use our MVMCP tickets when entering. We were given the wristbands at the gate.
I can't advise you about keeping that time. You know your party best and that would be something that they should decide.
