Did this mid December, the weather was unseasonably cold, it's not cheap, but every member of the party agreed that it was the best part of the whole trip. The guides were very charming and knowledgable (the 8 year old girl in our group had a bit of a crush on both the glamourous Nicole and the handsome Davis!). The first tour of the park is great with the added knowledge of the guides, and if you do it at/before the park is opening you have loads of opportunity to see the animals. The "jungle trek" on foot was amazing, especially the aerial walkways - one of the participants in our group was very nervous and they were very gentle and encouragiug with her. You get to do the Kilimanjaro safari, but with lots of time and special stops for photos - it was a bit of a buzz seeing the normal safari trucks moving on while we were still there and taking pics. The guides also take pictures as well, and they came out really well.
The meal is served in a small building out on the savannah, where you can continue to view the animals. It is a light lunch and fussy eaters/those that don't like foreign food might be a little offput, but it is presented beautifully in little metal cans (nicer than it sounds) and you get a little bit of education about the food as well.
It was worth the money in my opinion (although I wouldn't pay more for it).
