Hello Larissa,
How wonderful to be planning your dear husband's birthday celebrations with such a gathering of friends at the Magic Kingdom Park; I can't think of anything more fun!
The first thing I always suggest for all birthday boys and girls is to be sure to pick up a
free '
I'm Celebrating' birthday button from any Guest Services; wears of these buttons often get extra birthday greetings from Cast Members and sometimes even other Guests.
Advanced Dining Reservations for Table Service restaurants may be made up to
180 days in advance by speaking with a Cast Member on 407 939 3463; I recommend making reservations as soon as possible due to your proposed large party size.
It's as
easy as pie to order a specialty cake by calling the Cake Hot Line on 407 827 2253 to discuss your requirements and make payment; cakes can be delivered to most any Table Service restaurant on Disney property.
You may find some other fun birthday ideas by checking out
Customize Your Celebration.
I'm sure your husband will have a ton of fun celebrating on the 29th December in the most magical place on earth!
Have a great Disney day.
- Jane
