Greetings Christina!
I'm thrilled you'll be visiting the
Disneyland Resort soon and very excited about your dining reservation!
I've never heard of any issues with accessing a
dining reservation at the Park if the reservation was scheduled prior to the Park's opening.
Here's what you'll need to do: Arrive at the Park approximately 15 minutes before your reservation.
For the most part, the Cast members at the turnstiles will allow guests to access the general entrance area and Main Street, U.S.A., 30 minutes before the Park opens.
If you arrive at a time when guests have not yet been allowed inside, you can simply let a Cast member know you're there for your dining reservation. They will have a list of guest names with reservations and will confirm you're on the list before escorting you to the restaurant. Since this reservation is in the morning, you'll probably be heading to the Plaza Inn for breakfast with Minnie & Friends!
The
Plaza Inn is usually cordoned off before the Park opens but again, if you have an early reservation and you get there with a Cast member, you should have no problem entering and enjoying a delicious breakfast to include the popular Mickey waffles!
Thanks for visiting the Disney Parks Moms Panel.
Sending you Faith, Trust and Pixie Dust!
