I wouldn't imagine this would attract too young of a crowd (or many families): It's a school week, it's pretty expensive.
And it does sound pretty stupid.
And, no, I'm sure this isn't the only thing they'll do. But I wouldn't expect more than the actually anniversary date being a big deal. (MAYBE that entire week, but not too likely.)
If we're not having fun, then why are we doing it?
