Hi Amy!
Thank you for bringing this question to the Disney Parks Moms Panel. Wow. I have been in this predicament in the past on so many occasions! Although you scored a great Be Our Guest reservation, you will most definitely be pressed for time. I recommend that you arrive at Be Our Guest 20 minutes early. If they are able, they will seat you a little early. Be sure that everyone in your party has reviewed the
Dinner Menu and made his or her selections. Also, when a Cast Member comes to serve you, kindly let her or him know that you are ready to order because you are hoping to see
Wishes nighttime spectacular. Be ready to order food AND drinks as soon as the Cast Member arrives at your table. If I were you, I would also request to take the desserts to go. Although you may be able to make your way to the front of the castle before the show begins, you might still have trouble finding a good viewing location. The last time I was in Magic Kingdom in December, we were able to find a good spot in front of the Castle on the side of Main Street closest towards Tomorrowland.
Before preparing yourself for the mad dash through dinner, keep checking the dining availability! I have often been able to move my reservations earlier by 10 or 15 minutes which gives us just enough time to make certain shows.
I am sending Pixie Dust and Jedi Force your way hoping you are able to enjoy dinner at Be Our Guest and find a fantastic viewing spot to see Wishes!
