We LOVED Wild Africa Trek in AK. It was expensive but worth it. I almost cancelled before our trip, but so glad we went. It was the highlight of our last visit. We did the 10am tour and had a light lunch on the Savannah - I think earlier tours have more breakfast items offered. The guides took photos and we got a picture CD after which was great. We loved it so much we are doing it again next trip.
We also did Keys to the Kingdom but it wasn't our thing. I have friends that love this tour. It drug on a bit too long for us, maybe it was our guide (?). It was a very hot day and we had a lot of time standing in direct sunlight and my mind started drifting. The info we got on Main St and at the rides was great, but a lot of the info we received, I have seen on TV about Walt.......just my opinion. When we were in the Utilidors, they just pointed to pictures hanging on the walls and talked while we stood in the way of cast members......I felt like an annoying pest for CM's that were trying to get places.
