DW and I did KTTK in 2003. It was worth it. Seeing the backstage areas, the "good show/bad show" section, utilidors, and Haunted Mansion/Jungle Cruise with a guide was great. Our tour guide was Matthew, we think. He was great. Since we had an 0830 tour, we got to go into MK before it opened that day. Fund to watch everyone come pouring in when the gates opened. I agree with others: take the bottle of water they offer. You select your CHH meal before the tour starts. We also got a gold colored pin in the shape of a key to take home. Be prepared to walk! We were so tired after the tour (it was the first full day of our vacation) that we took the boat to WL, found a quiet spot on the 2nd/3rd floor above the lobby, and rested until it was time for our AP ressies. (AP was a wonderful meal, but DW was sooo tired that she didn't appreciate it fully until months after we returned home). Perhaps we should've made our ADR's for somewhere near the BC (where we were staying), or not planned on upscale table service for dinner that night.
