i went on the tour the time i was at WDW by myself (without DH, DD and DS).
i had to be at a conference in orlando, so i arrived 9 days early and did every behind the scenes tour (really, every one of them, including scuba in the living seas in epcot!!)
i liked all of them, but especially the backstage magic.
I know my family would have enjoyed it as well, as we're all the geeky types who love to know how things work (the behind the scenes organizational nitty gritty).
I definitely recommend it! I hope to be able to take my family on it one day!
