Hi, Marianna! Welcome to planDisney.
What a magical evening you have planned! Dining at
California Grill is always a special experience, and when paired with a stunning view of the
Magic Kingdom Park fireworks, it becomes truly unforgettable. If my wife and I want to celebrate a special occasion, you'll find us at California Grill for dinner and a show.
You're right that
Mickey’s Very Merry Christmas Party brings extra holiday magic to the skies, and you can certainly view Minnie’s Wonderful Christmastime Fireworks from California Grill (with magical music piped in). However, there's no Christmas party scheduled on November 15th this year (the Christmas party takes place on the 14th and 16th). That means you'll be treated to the regular nighttime spectacular,
Happily Ever After, on the evening of your reservation. The show is fully visible from California Grill, and the music is beautifully piped in throughout the restaurant and the resort's observation decks, so you can enjoy every note along with the view.
If possible, arrive a few minutes early and enjoy a cocktail or beer at the lounge. They have some delicious options, and I find it to be a practically perfect way to begin the evening. Once your table is ready, you can bring your drink with you and continue the celebration!
Mike
