I did Dayton last year. Unfortunately I'm on a boat with 2000 of my best friends, so won't make this year. The airshow there really took care of the the crews. We had cars, a good hotel room, food and drink at the show, and a crew event or party every evening for all three nights.
Dayton was pretty cool. the first night, we made the mistake of going downtown, which was dead, dead, DEAD! There's a bar/restaurant district, which has a name I've forgotten, that we went to the second night and was completely hopping.
All in all, I recommend going if you can score the CCX. I know most people think "Dayton? What the hell's in Dayton?" but it was a really good time.
