In your experience, what is a better, wilder destination for Spring Break, with crazier parties, more clubs, and more people: Panama City, Daytona Beach, or Ft. Lauderdale?

I'm a guy in his 20s and I'm looking for a wild place with lots of girls and alcohol, of course.

(From what I understand nothing beats Cancun, but I'm not considering it now because I don't have a large group going and the costs are too high).

So: Panama City, Daytona, or Ft Lauderdale? All comments welcome. I'm going with a friend.

And also: Is it just as good at the end of March (22-28) as in mid-March (11-18), or no?
