Our ADR is at 9:20 for CP breakfast. As we are staying off property, can we get in a bit early to meet this time. The park opens at 9 and I'm not sure with the crowd and security check, if we can make it.
The gates to the parks actually open about an hour before the official park opening. The rides are not open, but the gates are admitting guests. Some of the restaurants open before the parks also. You should have no problem getting in about 8:30. Just have your ADR confirmation number with you "in case."
There is always one turnstile which is open for people at early dining. Before you get to that turnstile (which is well marked) there will be a person with a list to verify that you do have a reservation.
