Personally, it wasn't our favorite. We thought it was a bit long and too much standing in the hot sun. They gave some great info, but we were bored and waiting for it to end. I knew a lot of the Walt info from TV shows I have watched before. My fiance was waiting for the utilidors part of the tour, but you just stand there while the guide points at some pictures and then you watch a video of how the costuming department works. We were in a lot of CM's way the whole time while we were down in the utilidors and I felt bad about that. The info they gave you during the private Jungle Cruise was great. When we got to the Haunted Mansion, she told you a lot before you went on the ride, but my brain was over it by then.
That being said, I have a co-worker that loved the tour and did it a second time, with friends.
We LOVED Wild Africa Trek in AK, it was more expensive but well worth the money. We are doing that again on our next visit. Such a unique experience and they have a photographer with you and get the pics at the end. Last year they mailed you a CD with your pics, but I believe they recently changed it so you can download them with a password and link they give you. You got close ups of the hippos and the walk over the rope bridges was cool - Disney safe. Your tour group gets their own safari vehicle/jeep and pulled over to see animals where regular safari jeeps don't. I think we had 16 on our tour. Much more personal and lots of info. Depending on the tour time, you get a light meal (breakfast or lunch) on the savannah overlooking the elephants. Excellent memories!
