As a grand gathering I have done the safari dinner at Animal Kingdom
You get a "private" safari with the other grand gatherer's, then a buffet dinner with characters and some of the exotic animals to see the children there is an african band playing with dancing for the kids and adults who want to join in and keepsake pin.
Illuminations dinner there is a comedy show and character greet with minnie & goofy. Buffet style dinner, private viewing for the Illuminations show and desserts with coffee, tea, juice. Keepsake pin too.
Those are the only ones we have done loved them.
