My wife suffers from sinus problems. We live in Michigan, and go to Florida for winter breaks. We are interested in spending a month in the driest area of the country so that we can find too see if low humidity helps with her condition.

Our plan is to rent a condo for the month of May or June, 2009. Because my wife will be alone for a portion of the time, I am looking for the safest, nicest area. What is the nicest area to look in?
