"One day soon, Colton and I plan on joining the Mile High Club, so fucking this many floors up in a condo is kinda, like, practice for that," said Karina, 24, a casino worker from Las Vegas who was staying over in Miami prior to taking a Caribbean cruise with her man. "We're going to be getting lots of exercise on the cruise, but it won't be from rock climbing or swimming or riding jet skies; it will be from screwing every chance we get. Our cruise is going to be just about eating, sleeping and screwing."
