I've been on the KTTK, Yuletide tour, Segway (twice), and Backstage Safari. In a little over a week I'll be doing Backstage Magic and Wild by Design. The one I'd least recommend is the Yuletide Tour. While it's true that it's only offered around Christmas time it was my least favorite tour. They took us into the warehouse where they store all the Christmas decorations, but it was almost empty because all the decorations were out in the parks, we got a little history of the Christmas tree in Germany, and also the decorations in the American pavilion, and we saw the decorations at the Grand Floridian and got a free piece of gingerbread, but that is about all I remember about it. I was ready for it to be over, way before it was. The KTTK on the other hand I loved. It's a great first tour and we got tons of information on it and got to see the Utilidors. It really gave us an appreciation of all the details Disney puts into the parks. The Segways are just fun, plus we got some info on the world showcase. I did this tour twice. The first tour was much better than the second, because the tour guides were older and was really interested in imparting info on the park and about each country. The second time, we had a couple of 20 y/o somethings who seemed to be just going through the motions. The Backstage Safari was wonderful. We got to see where the vets work on the animals, where their food is prepared, and where they are kept at night. We also got to pet a white rhino and a spiny lizard. I'd recommend either Backstage Safari or KTTK to anyone.
