I decided to take everyone's advice myself and went to see Spring Awakening tonight. It was good, but yikes, I think it would be seriously uncomfortable for parents and young teens to see together.

I saw Hairspray and recommended it. I was disappointed in Grease.

I second the vote for Spamalot. We've seen the one in London and the entire family was laughing constantly. Very funny, but you have to be a Monty Python fan I guess to appreciate most of it.

I don't see that anyone mentioned Wicked. I know what you're thinking, but my son said it was okay and the rest of us loved it. We've seen it 3 times now.

Stomp is very loud, but very entertaining as well. It is easier to get tickets for as well.

Look up broadwaybox online for great discounts on all shows. I use it for NY and London.
