I second his opinion. You get a lot of history and information. And you get to brag to everyone that you have been backstage and in the utilidors of the MKIf you have the time? DO THIS. It's a GREAT tour... backstage areas, Utilidors, one or two rides with history & backstage data... and definitely not for the children .
I thought this was one with an age limit. Maybe I'm wrong. But I thought you had to sixteen years old. Either way, I wouldn't take a kid who isn't accustomed to doing tours or who was under twelve.
Only you can decide if you want to take time out of the parks...but I'm not sure it's a good idea. If you're even thinking you might want that time, I'd use it.
It's an okay tour. For people who aren't huge Disney geeks, I give it a B+.
