Hi Robert,
Have you considered booking a Character Meal to celebrate your boys birthdays at all?
If so, Donald's Dining Safari Breakfast or Lunch at
Tusker House in Disney's Animal Kingdom would be a great idea.
Breakfast is served from 8.00am - 10.55am and Lunch is served from 11.00am - 2.45pm each day.
On arrival at the restaurant, you will be greeted by Donald Duck and once seated inside the restaurant, you will be visited by Daisy Duck, Mickey Mouse, Minnie Mouse & Goofy at your table whilst enjoying a delicious buffet breakfast or lunch. (Please do note that characters are subject to change without notice.)
Other places where you can normally find Donald Duck include the Camp Minnie-Mickey Greeting Trails at Disney's Animal Kingdom and in Frontierland (by the Liberty Square Riverboat) at the Magic Kingdom.
Characters and greeting times are always subject to change so be sure to pick up a Times Guide as you enter each Theme Park and check the Character Greeting Times section for up to date information.
Lastly, whilst at the Magic Kingdom, be sure to stop by the Mickey's PhilharMagic attraction in the Fantasyland area. It's a 12-minute 3D movie starring Mickey Mouse and Donald Duck that features scenes from classic Disney films projected on one of the largest seamless screens in the world. An absolute must-do for any Donald Duck fan.
Wishing you a magical trip filled with memories which will last a lifetime!
