Family style meals include 'Ohana, Garden Grill, Liberty Tree Tavern (dinner only), Hoop De Doo, Spirit of Aloha Luau, and the family platter at Whispering Canyon Cafe.
You can order from the kids' menu at any Quick Service restaurant because there's no way of knowing who you are ordering for. At Table Service restaurants most will allow anyone to order from the children's menu, but once in a while someone will post that a server or restaurant followed the "Ages 3 - 9" that is printed on the menu so it is best to ask first.
You will be charged according to age at buffets, family style meals, fixed price meals (e.g. CRT, Akershus), Dining Packages (e.g. Fantasmic, Candlelight, Jungle Book), special events (e.g. fireworks parties, F&W events), the 3 dinner shows (Hoop De Doo, Spirit of Aloha Luau, Mickey's Backyard Barbecue) and the Family Platter at Whispering Canyon Cafe.
