Hi there, Kathleen!
'Ohana, one of the most fabulous experiences you'll have, offers a variety of delicious "grown up" food; I know the temptations of that menu are much stronger for may children than the standard younger-diner fare!
When you pay out of pocket, you can purchase almost any menu item/s you like for any member of your travel party. The exception to this is that Cast Members have the prerogative to enforce Disney's policy that does not permit an adult to order from the children's menu. A child can always order from the adult menu.
Cinderella's Royal Table is an all-you-care-to-eat pre-plated breakfast, served to you while Princesses and members of the Royal Court circulate throughout the room (entertainment subject to change).
Remember to make reservations
online, or by calling (407) WDW-DINE.
Have a wonderful time!
See you later, celebrator,
-Deborah B.
