I love a good travel contest, especially one that requires little effort to enter. So I'm excited about the jetBlue and Hertz Jet & Drive Giveaway, which runs now through through January 31, 2010. To enter, all you need to do is surf on over to the website, complete your free registration and then enter your email address. Easy, peasy.

For that minimal effort, you could win some pretty cool prizes, depending on the number of entries for the day. Yes, that's right - the prizes will vary according to how many people have entered for the day, and you can enter every single day of the contest. If 2,500 people or less enter on a given day, the winner gets a $100 Hertz rental card. With 2,500 or more entries, the card's value goes up to $250. But if 5,000 people enter, the lucky winner gets a $500 jetBlue gift card!

There will also be up to five grand prizes given away, one each time the total number of contest entries reaches another 50,000 milestone. The grand prize includes airfare to one of five destinations, Hertz rental car, and accommodations at a designated Starwood or Marriott hotel for two people. Destinations include New York, Las Vegas, Los Angeles, Orlando and Aruba.
