It's freezing outside, and you need a tropical vacation. You can score a trip for free by entering King Kamehameha's Kona Beach Hotel giveaway. If you win, you get a three-night stay in this newly renovated posh hotel, plus $100 for food expenses. And if you miss the boat this month, don't fret--the contest starts anew every month in 2010.
This hotel is the headquarters of the Ironman Triathlon World Championship, so aim for the days surrounding October 9 if you want to get in on the ground floor of the action.
