Hi April,
I have heard only good things about the
Wanyama Safari and Dinner at Disney's Animal Kingdom Lodge and hope to experience it for myself during an upcoming trip.
There is a great post on the Disney Parks Blog
HERE all about this adventure which is available exclusively to Guests staying at Disney's Animal Kingdom Lodge and Disney's Animal Kingdom Villas.
As far as I am aware, as the whole experience is a set price per person, the Disney Dining Plan is not accepted as part payment for dinner at Jiko - The Cooking Place following the Safari itself.
The Wanyama Safari and Dinner can only be booked by the Disney's Animal Kingdom Lodge itinerary planning office or the Disney's Animal Kingdom Lodge Club Concierge at (407) 938-4755. Should you have any further questions about this experience, I am sure that they will be only too happy to help.
Wishing you a magical trip!
