What Larry said, plus: It's quite easy to move back and forth between, say, the Bahamas in the winter and New England or the Maritimes in the summer. I've done it a dozen times and average less than two months in the transition. That's with only one or two overnights. When I've gone further south, the Virgins or Belize, I've still made it back to Maine for the summer. If I went any further south, I'd probably keep going and spend the summer south of the hurricane zone.
