Florida might be OK, if you stay north of the I-4 corridor and away from the coasts. Also the panhandle area of Florida rates actually drop in the winter. Their high season is summer vacationers from the southeast area.
For any of the Atlantic or Gulf states, the farther you are from the water, the lower the rates will be.
