Hello, Jen!
Aw! It sounds like you and your family are pretty awesome folks and know how to add a little pixie dust to an already magical Walt Disney World Resort vacation. I like your Disney style!
You can't go wrong with a celebratory dinner at California Grill in Disney's Contemporary Resort. One of my favorite celebrations was dinner followed by the incredible Magic Kingdom fireworks just a few years ago. It's truly a storybook moment when the lights dim and the music begins to play.
Just last year, Disney announced
new Mickey Mouse celebration cakes available at Disney-owned and operated table-service locations. Not only are they absolutely adorable, but I've heard they taste great, too! The cakes are available in chocolate or white chocolate and feed around 4-6 Guests. If you have a larger party, I believe you are able to order additional cakes.
California Grill also has a decadent dessert menu, so you can always order from it as well.
Happy dining, Jen, and please let us know if there is anything else we are able to assist you with.
Magical Wishes,
Lauren
