Hi there, Twyla!
Thanks for stopping by with this great question!
You'll be thrilled to know that having a very early
Advanced Dining Reservation will allow you to enter Disney's Animal Kingdom before the Park actually opens to the public just like
Extra Magic Hours will! It's truly an amazing experience to enter any of the Parks early when there are very few Guests about. As you approach the Park entrance, look for the sign that says something along the lines of "Early Breakfast Reservations." If you don't see it right away, just ask a Cast Member and they'll point you in the right direction.
I'd also like to advise that you arrive at the Park entrance about 30-minutes prior to your reservation time. You'll want to take your time walking back to
Tusker House Restaurant so you can stop and look for animals waking up on your way into the Park.
I sure hope this helps, Twyla! Feel free to let us know if we can help with any other questions you have!
Wishing you a Pixie Dusted vacation!
