For us, it was well worth the money! Again, we knew about alot of the stories our guide told us, but he made them sound so nw and exciting. He also told us lots of tales and tid bits of information we didn’t know which was great!
Going backstage was exciting, though not as glamorous as you might imagine. Behind the scenes, it really does look like a work enviroment (though how else would it look? lol). I only say this as I have heard people in the past complain that the tour has taken some of the shine from their trips, but they do tell you before you book that you might see some things you might not like (mostly with regards to the characters)!
For us, it has only aided in adding to our experiences at WDW. On my past trip with my very non-disney bf, I was able to point out little bits and bobs I had learnt on the tour that really interested him which was great! We talk about the tour often and the things we seen / learnt. Yes, it’s a shame we couldn’t take any pictures, but in a way, I like that. I like the fact that the majority of the tour hasn’t found its way onto YouTube etc! It makes you feel like you have something secret and special!
