Vacation to the Beach suggestions

Hi everyone....This is the easiest way I knew to get a(hopefully) some help with vacation plans. We want to go to the beach either in N.Carolina (southern) or S. Carolina. BUT we are hoping that some of you know of a location that is not quite so heavily congested with tourists. We have been to Nags Head, and Myrtle Beach, loved them both, but a lot of people. I have heard of Ocean Isle S. Carlolina, anyone familiar with it? If anyone has any ideas for us please let me know. Thanks for you help. Chris
