We did this tour in October 2014 and had a great time. You meet in MK by the tomorrow land cafe (that is never open) and then after they get you signed in, give you a lanyard, and a name tag, you are off to several MK rides. We rode, Pirates, splash mountain, big thunder mountain, haunted mansion, seven dwarfs MT, space mountain, and buz light year. We then left the park through the back lot in a waiting van and went to Hollywood studio where we rode star tours, toy story mainia, rock and roll, and tower of terror. While there, we had lunch (included in the price) at brown derby. We left again in the van and went to Animal Kingdom where we rode expedition Everest and Dinosaur.
After you are done, they will take you back to MK or the transportation center. The guides are really nice, they have water with them and constantly offer it to you along with different suck on candies.
We finished the day by going to Epcot where we had FP+ reservations and rode the rides there so you can really hit all the major rides in one day.
We will do it again for sure.
