Hi Darnell, and welcome to planDisney! I’m happy to help you plan your magical vacation to the Walt Disney World Resort!
You absolutely can change your
Disney Park Pass reservation to line up with your dining reservation at
Be Our Guest Restaurant! I’d just make sure to first check the
Availability Calendar to see if you're able to book the day you were hoping to visit instead. This week especially, with many schools here in Florida out for Spring Break, Disney Park Pass reservations have been a bit hard to come by. I’d hate for you to cancel your existing
Magic Kingdom Park reservation and find no availability for the subsequent day. If you're finding that there isn't availability for the day you want to visit, I suggest you hang onto your existing day and keep checking the Availability Calendar to see if any spots open up. That way, at least you’ll still be able to make it into the Magic Kingdom at least once during your trip.
Darnell, since
Park hopping has returned, you could also try to hop over to the Magic Kingdom in the afternoon from another Theme Park. Disney usually opens Park hopping hours at 2 p.m. each day, subject to availability. You’ll need to have the Park Hopper option on your tickets, but you don’t need a Disney Park Pass reservation for your second Park of the day. Just be aware that a dining reservation doesn’t guarantee entrance to that Park if hopping has been closed due to capacity.
I hope this helps you make the most of your Disney days, Darnell. Please come see us again if you have any more questions!
Keep Disney Dreaming,
Kathy K.
