Second that. My exchange tour was a blast (not that this is strictly an exchange, as I understand it). The chance to immerse yourself in another culture, see how another Air Force operates and then, in 3 years time, sort the wheat from the chaff is one not to be missed.
As for Vegas, yep, it's a helluva town, but as alluded to, nowhere is far away in these days of cut-price air travel. If you're considering it and don't apply, you'll be asking youself "what if?" until the day you hand back the blue suit.
