There's every chain hotel and restaurant near the show. The show is in St. Charles, so for "culture" you'd probably head to Chicago.
The best "deals" are found usually on Sunday afternoon, close to the end of the show. Walking around, the prices often seem high...great deals are also found Friday night, before the show, with a VIP pass.
There are usually good deals on cymbals (and a vast selection), vintage parts, and also new and custom drums, parts and accessories.
I've been going since the second show, many years ago...now I go more to see the other vintage drum friends I've made, and to see the clinics, which all usually real good to amazing.
One bit of advice, is, if you see something you want, buy it! Every year I leave and think I should have gotten this or that...and often regret not buying something. There's so much stuff there that it gets overwhelming...if you would see any one of the snares or sets in a local store near you you'd grab it, but when you see so many together they don't seem as special. Try to look past that.
Even if you don't buy anything, there's acres of drums and drummers...only one thing could be better!
