I'm still working on finding that old thread for you on Jacksonville. In the meantime, you might consider driving to Ponte Verde and possibly St. Augustine to see the fort there, if you're at all interested in history. There are also a few shops in St. Augustine and some nicer shops in Ponte Verde. If you golf, Ponte Verde's the place to go.

The whole area's not too exciting, but there are some day spas you might want to consider.
This one's in Jacksonville:
