Guaranteed Admission with CP tickets

[ToniH]

We have tickets for CP on 12/24 - I've been reading that crowds are huge at this time and the parks close admission to new people early in the day.

If we want to go to MK in the morning will we be able to enter Epcot for CP and our dinner reservation if it's closed to new admissions?

Trying to plan our day!!!

Thanks.

Toni
