I'm considering upgrading a ticket for next week to an AP, but I need to clarify something. We want to be at AK on the Saturday morning and MK on Saturday night. Disney says something about not being able to enter MK after 2 on Saturdays and Sundays without a park reservation. Does that apply to all APs or just someone who hasn't had a park reservation at all on Saturday? In other words, would I need to make a reservation for MK on Saturday and scan in there before going to AK in the morning or will having a park reservation at AK make it possible for me to park hop to MK Saturday night?
