Both. Just seems like a cool experience. Also if it sucks you can always just wander off and have a blast. AC is almost limitless with fun sometimes.
I agree.
I went to a concert in AC a year ago. Gig ended around 2:30, but the band weren't interested in going to sleep, so they stuck around the casino floor for a while. Apparently this is nothing new for them, as they're big fans of Las Vegas, and some even live there.
