I just got back and wanted to let you know that Walk in Walt's Footsteps was a neat tour! It's 58 per person and with that you get a tour for 3 hours, a pin with the tour's title on it, and lunch. You also get to ride 2-3 rides where you walk right up and get on with no wait. We did Jungle Cruise, watched the Tiki Room show, and rode the train. The information our guide had was amazing and she told us a lot of things we didn't previously know. We also got to go into the lobby of the infamous Club 33 and take pictures and such.
It was worth it to me, but I think that now that I've done it, I wouldn't pay to do it again because while a different guide may have different anecdotes or information, the general gist of the tour remains the same.
I say go for it.
