I'm one of those people who has to do everything there is to do that's Disney. I've been on every tour and I think it taints me to a degree. I think most of the other tours are better. If you don't have anything else to compare to then I suppose you could like this tour.
I found our guide misleading. She would make up answers if she didn't have one. We caught her in a few lies. I reported her and I was very careful to spell it all out. I never had that happen on any other tour. One redeeming part of the tour is you get a keepsake at the end of the tour which was a nice touch.
You do go to all the parks and we were in Epcot World Showcase before it opened and I loved seeing the place totally empty except for the tour group.
Many will probably say this is a wonderful tour but I'm not one of them.
