It is actually called Bush Camp.
Starting on March 24th, 2007 Disney's Animal Kingdom Lodge has opened its kid's program, Bush Camp to all guests. Bush Camp, a 3 hour experience for kids ages 6-14, will teach kids about African Culture through games, activities, food and crafts. The children will also get to explore animals on the savannah, and "play along" with a character from "The Lion King".
The cost for Disney's Animal Kingdom Lodge Bush Camp is $70 plus tax per child and hours are from 1:00pm to 4:00pm every Saturday. You must guarantee your reservation with a credit card. You must cancel more than 24 hours in advance for a refund. $20 of the cost is donated to the Wildlife Conservation Fund. DVC members receive a 10% discount.
The program can be booked by calling 407-WDW-PLAY.
PS I actually booked this and the only way I was about to book it was thru WDW Dining not thru WDW Play like all sites have directed.
