I went to my ten year. On Long Island, that's typically what the schools start with. My ex's and mine were both scheduled for the same weekend at the same hotel (Friday and Saturday). I paid for both, then two weeks later, we split.
It was pretty good...most of my friends from school weren't in my class, and the friends that were didn't go. Still, I enjoyed it.
If my twentieth wasn't scheduled for when I'm moving to Florida, I'd probably go to that one. Have a feeling I'll be waiting until the 25th to go back.
