I love the tours, have done all the tours and most of them multiple times. It's a great way to learn about the parks and see things that you normally would not get too.
If you're going during the holidays the holiday tour is great. Vip seats to the parade, rides, hot cocoa, gingerbread cookies and the special pin.
The happiest haunts (which isn't offered right now) I just did. We got to ride big thunder, Peter Pan, Matterhorn, space mountain, and haunted mansion. Treats, the pin, and a death certificate.
Walk in salts footsteps now goes into the dream suite, rides vary.
The California story, is all in DCA and you get to go into 1901. Soarin, toy story mania, and radiator springs.
In January my friend and I are heading to Orlando and will be doing backstage magic. Hope it's as good as the California ones are.
