I second everything that Shammy said
You have to be willing to go up and at least say hi to people if you want to meet anyone.
Another way to meet some of the expats would be to volunteer at one of the local organizations, PAR, Coco's, or others. I've met some great people (tourists and expats) doing this. And this year PAR will be open when I'm down there... YIPPEEEEEEE!!!!!
