I like to take the Free Family Deal by whats known as the parking-lot lotto. You wait in the parking lot of the hotel of your choice until a guy comes out to a mini-van full of kids, wife and luggage, take his hotel key, and burn their bodies in the van somewhere in the Everglades. Its usually a seven day, six night package, with two rooms and gate passes.
If they only have the four day, three night - do it twice.
Its very economical, and theres always loads of extra goodies. iPods, bonus cash, laptops. You really can't beat it.
