My husband took the Walk in Walts tour last year. He really enjoyed it. It came with lunch, and they mailed us a neat pin after the trip. The highlight of the tour was the visit to the lobby of club 33.
A month a go we took the VIP tour. Its expensive, but worth it! Its a min. of 4 hours, $75 per hour. YOu can have up to 10 people for that rate. They will design your tour around what you want to see and do. For us, she was our fast pass "runner", got us to the front of the line for some characters, got our dd picked for Jedi training, rode the Lilly Belle car on the train around the park, and we had reserved seating for a parade and fireworks one day and a couple of shows/ parades the following day. Really, a lot for the money, especially for 6 people.
We wanted to do the discover the magic tour, but they were not offering when we were there. I've heard it's great if you have children.
