Count me as another vote for Prom. Of course, if anyone in your group has problems with homosexuality or two girls kissing then they won't like it, but to any reasonable person it's a nice story, generally uplifting and a lot of fun.
Also, I think the 10 year-old will really like the dancing. I mean, I'm 42 and I really enjoyed it, and I don't see any reason why a 10-year-old wouldn't. :)
Oh, and to your question on tickets -- we saw it in May when my parents were in town, and got them though TKTS. I don't think it will be a hard ticket to get, so I'd look at the various options. But not something I've followed at all.
