What about the Gulf Coast? It's not as warm as south Florida, but there's beautiful scenery, nice history, and some good inns (this is all hearsay--I've never actually been there but my parents like the area for the history and food). I've read a couple of Crazy Guy journals from people who have toured down there in the winter--services are quite scarce, so day trips are probably best (people had difficulties finding food on self supported tours) but the roads seem nice and pretty safe. Average temperatures along the Gulf Coast in the winter are pretty much what we're getting here now--40's at night and mid-60's during the day. I consider that perfect cycling weather!
