Finding the right spring break package first requires you to figure out where you want to go. The whole southern half of the US is rife with spring break destinations, all offering variously priced package deals, so it behooves you to check out as much as you can before you make a decision one way or another.
Some of the things you should look for in a spring break package are pretty obvious: Make sure you get a good price on a flight and a hotel. Make sure that the hotel (or villa, or house you're renting, or whatever) is actually situated close to where you want to be. You'd be surprised at how many spring break package deals are out there designed to prey upon vacationers who didn't do their due dilligence. If you've found a spring break package where the price is too good to believe, then don't believe it - chances are, the price is that low because there's something fundamentally flawed with what's being offered.
It's also important to understand that, while spring break isn't exactly a once-in-a-lifetime event, it's not the kind of thing you want to cheap out on. Don't go for the cut-rate price to Daytona Beach (which is deader than dead) when, for a grand more, you could go to South Padre Island or Lake Havasu. Or if your passport is up-to-date, to Cancun or Cabo or points beyond.
Spring Break's heyday was actually in the Fort Lauderdale, Florida area back in the 1970s and 1980s. Every year the city would play host to more than a quarter million students from around the United States and Canada, and activities ranged from the ice luge to the after-hours emergency room visit to figure out just what, exactly, that rash is.
Eventually Fort Lauderdale cracked down on underage drinking and binge drinking in general, which puts quite a damper on the typical spring break goals. Soon Daytona Beach offered a yearly spring break package that was unrivaled, and played host to MTV's annual spring break celebrations in the early 1990s. However, after a few years, some rather sad deaths and bad publicity, Daytona Beach cracked down in much the same way Fort Lauderdale had previously.
There were other places willing and ready to step in and fill the gap, though. Panama City Beach, Florida, is one. For whatever reason, they haven't cracked down on the type of drinking and "sinful" activities their Florida neighbors did away with over the years, and as a result it's the premier destination for spring breakers from the midwest, northeast, and most of the southern states.
