Where should I go to busk in the American South?

I am a 23-year-old -female working predominantly as a street musician. I play solo accordion. So far I’ve played in particularly artsy parts of Massachusetts as well as San Francisco, and in these places I can do well enough to support myself.

I’d like to spend the winter (mid-January through April) busking (street performing) in the American South, a territory that I have not explored. I’m trying to find the ideal city, and I’d like suggestions!

My requirements:
-Warmer than Massachusetts
-Tourists/ample foot traffic
-Art/music scene
-Safe for me to walk home alone at night
-NOT a premier music city, simply because I’m not good enough (Nashville, Austin, New Orleans. Also not Key West since it’s tough to get a permit.)

So far people have suggested Savannah and Charleston. Any suggestions or ideas would be greatly appreciated!

Thanks!
