South Padre Island, TX is your answer.
South Padre Island is THE PLACE to be for spring break, especially if you're a Greek, and there's a few reasons why.
Big condos can hold big groups, and Inertia Tours has entire condo complexes to hold entire Greek systems from college campuses. If you want a to stay together with all your friends, this is the way to go. Plus you get your own kitchen and living room which is ideal if you want a place to have a private party of your own.
The beaches here are the most scenic in the U.S.! Also, you can have open containers including kegs on the beach, making it ideal for spring breakers. The weather is 10-20 degrees warmer than Panama City on average during spring break, so it beats out Florida.
Another reason why South Padre is the best is because of the activities available, such as the booze cruise (above). There's tons of extra stuff to do like skydiving, learning to surf, and the HUGE spring break parties put on by Inertia Tours. Lots of times we even get people from MTV to come MC for us.
Inertia Tours has the best value for spring break trips, hands down. We have packages for under $500 per person so no one has to get left behind! Inertia payment plans are custom set up for Greek Groups. There is also the ability for each person to pay online with Inertia using their own credit card while still on a group booking, so no one person has to handle all the money.
We have been bringing Greeks on spring break trips for a long time, so we know what we're doing! Bring your fraternity or sorority on the best spring break trip of their lives.
