Camp site in South Padre, TX or Gulf Shores, AL

We had such a great time at the beach in Galveston this weekend that I can see that I need to plans the boys Spring break on a beach. Spring Break is in March and I know that South Parde, TX and Gulf Shores, AL have great beaches. Can anybody recomend camp sites in either of these areas? I chose these sites due to distance from Houston - If anybody knows of any other great beaches closer - I am open for suggestions!!

Thanks GM
