We loved the Brac when we were there, but we plan to go back to the places that make our "short list" with more of an eye towards living vs vacationing. We also intend to rent rather than buy real estate, so that we have more flexibility/mobility.
(in case you're interested, the short list so far also includes Belize, St Croix, maybe St Lucia, but still very much in research mode!)
Thanks again, you're a great resource!
