Coming over from England to Vegas for 5 days in March, with three other guys. I want to have a thing to do every day that I could only do in Vegas. I mean obviously one can say gamble, but I could do that at a casino anywhere. So can anyone think of 5 unique things to Vegas I should do? (I was thinking of taking my girlfriend over to get married by Elvis in a chapel but I think might be taking the game too far!!).
