I personally don't plan to come within 500 miles of Vegas during the Super Bowl, but for those of you thinking about it, I was rather surprised to find that the 4Q is charging "only" $299 a night for the three-day weekend. Plus tax, of course, but no resort fee--and a 10% senior discount to mostly offset the tax. So you can sneak in for $1000 or so for the weekend.
Now, actually attending the Super Bowl is a feat orders of magnitude more difficult and expensive, but if you want to be in town for the madness, this is a not overly crushingly expensive option. Me, I can stay home and buy a LOT of pizza and beer for that kind of money. But it'll be a while before the Big Game is in Vegas again, so...
