We are originally from Fla with cruising experience in the Bahamas/Carribean.
We recently returned from the Portuguese 'Algarve' (east/west coast of Atlantic Portugal) and are returning to stay permanently. We particularly like the Rio Guadiana separating Portugal and Spain. This international boarder-river has numerous cruisers/liveaboards, most about 20 NM up river at Alcoutim (Portuguese side) and Sanlucar (Spanish side).
