If you have a PS for CP in MK before the park officially opens, do you just walk up to the gate and show them your PS # and they just let you in? You don't stand in line.
We had PS at CP before the park opened we did get to go to the front of the MOB at the gate and yell to the lady that we had PS at CP. She allowed us to go through. My advice would be get to the gate as early as you canso the crowd is not too large. Good luck!
If you go into the left - there is a team of people with a list of all the PS's for CRT and CP. They will let you in and it feels like you have Main St. to yourself. Nothing is open yet.
No - you can mill around until the areas open - there are official mini-openings at all of the little parks - tomorrowland, fantasyland, etc. It is difficult to get through a character breakfast in under an hour though.
Another question - How soon/far in advance of your PS do they let you go in the park to the restaurant? Would it be only for those that have ressies BEFORE the park opens? Would someone that has a PS for 9:15 will have to wait outside the gate? I am glad my PS is early.
