It appears both of us will retire in our house next year. Hopefully, Janet in the Spring and me in the fall.
What we have found is the best deals are last minute (i.e. 3 or 4 weeks before) on our Europe excursions.
Austria, Spain, and our last one to France were all done 5 weeks or less before.

Jealous of your sail plans. Have you ever thought of doing down around Guadeloupe & Marie-Galante?
We never sailed there but really enjoyed our time on island.
But understand the BVI desire - Sometimes some place new is exciting and sometimes returning to the known is the best.

As for your next foray to the continent - NW Spain
We are going to make a wine drinker out of yet.
