It wasn't our favorite thing but it was fun and if we'd done things a little differently, I think we would have liked it more
I would recommend it if you have more than one morning scheduled at MK. Because of when its scheduled, you miss most of your rope drop opportunities to do the tour. I'd also schedule it at the end of your trip. We did it at beginning of a trip and the kids didn't like walking by all the attractions.
I'm pretty sure the attractions you get to do varies. When we did it, we met Minnie & mickey and Peter pan and we rode pooh and I believe one other ride.
We went in May and it was hottttt. I don't think I'd do the tour in the summer months.
