Hey there, Kristie! Welcome to planDisney.
How wonderful that you have planned an amazing dinner in the splendor of Beast's enchanted castle! I'm not sure if you will be traveling from
Disney's Animal Kingdom Theme Park, or if you meant
Disney's Animal Kingdom Lodge, but either way, my recommendation would be to travel using Disney's complimentary
bus transportation. A good rule of thumb is to allow about 90 minutes for transportation, so I would say plan on departing around 7:30 for your 9:00 pm reservation. This would allow plenty of time in case you need to wait for a bus and to make your way to
Be Our Guest Restaurant for your reservation. I think bus transportation is your best bet rather than driving or using a ride-share service, as buses will drop you off right at the front of
Magic Kingdom Park. If you happen to arrive a bit early for your dinner, take some time to capture magical
Disney PhotoPass photos with your group. You'll find photographers in several locations along Main Street, U.S.A., and also near
Cinderella Castle. Did you know, you can find Disney PhotoPass locations in the
My Disney Experience app? Use the location button at the bottom of the home screen. The default view is "Wait Times" at Magic Kingdom Park, but you can use the drop-down menu at the top to select "PhotoPass". One of my favorite PhotoPass locations in Magic Kingdom Park is Liberty Square Bridge. This location has a unique view of Cinderella Castle that is usually not too busy and is right on your way to Be Our Guest.
I hope that helps! Please stop by and see us again if you have any additional questions. Enjoy your visit!
