Yes, some years ago.
I believe it is only open to guests staying at Animal Kingdom Lodge or Villas. They take about ten to twelve guests per event and children must be at least 8 years old.
That said, it was a great experience, I thought. The "safari" was fun, you learn fun facts about the Lodge's animals, and you have a group dinner (with your entire safari group) at Jiko, where you get to try a number of their specialties served family style, and wine is included. (If you are looking for a private dinner with just your party, this isn't it)
