We did the Family Magic Tour in January. DD5 absolutely loved it, as did DH and I. In my opinion the ideal ages for this tour are maybe 4-12. We had a wide variety of ages on our full tour. I'm pretty sure ALL the kids in this age group and ALL the adults had a wonderful time. There were 2 little kids including DS3 who did NOT enjoy the tour. Although we went on the 5th day of our trip, DS3 was really upset about not getting to go on all the rides we were passing and the story and most of the games were above his level. There were also 2 teens (~15 or so) who while they were good sports and certainly didn't ruin anyone's fun, you could tell they were embarrassed and would rather be elsewhere. I'd definitely recommend reading the review and warning your teens about the silliness they will have to "endure."
We got a great family pic with Peter Pan and Wendy and DD got to sit next to Wendy at Mickey's Philharmagic. It was a great time but DH and I agreed that we wished one of us would have stayed with DS3 and taken him on rides instead. But WE both enjoyed the tour very much!
