Hi, Marlin! What a special milestone birthday your party will be celebrating and in such a fantastic way! I can't think of a better place to commemorate it than aboard a Disney ship!
To make someone's birthday extra special on Disney Cruise Line (DCL), make note of the birthday person on your reservation. You may also discover some additional ways to celebrate by checking out
DCL's Gifts & Amenities Page. You can pre-order everything from cakes, gifts, food or flowers to be delivered to the guest in a stateroom or table-side on a particular cruise day.
As for your birthday meal options, you can not only make note of the birthday on your reservation, but you can of course alert your waiter for a particular evening during Main Dining. Aboard the
Magic, I recommend either Animator's Palate (festive and somewhat casual) or Lumiere's (French and more formal). If you happen to be dining with adults only, Palo is worth the extra cost and reservations -- for dinner (any cruise) or for brunch (4-night cruises or longer).
I hope this helps you plan! Let me know if I can be of further service to you, and have a beautiful day and a magical vacation. Bon voyage!
