I thought I would share with you an experience that I had last summer, and intend to repeat this: the Croatian coast. It is spectacular and ideally suited to people with boats like ours. The coast is lengthy and is fringed with 1135 islands so it is is no problem to get your very own bay (or even island) to yourself, when you go off exploring each day. Unlike a lot of coastlines it is dotted with hundreds of small villages and is most definitely not dogged with the Blackpools and Benidorms of this world. Island and quaint fishing port hopping is simple.
I could go on forever about its plus points and it is not that far to take your boat. Get and early morning ferry to Dover, drive to Munich and stay overnight (Munich Marriott has great rates compared to UK Marriotts - around 70 Euros), then the next day down to Ancona and get the overnight ferry to Split, Zadar or Dubrovnik. Alternatively drive through Italy to the northern part, Istria.
If anyone is interested I can advise in much more detail. I vist the area with work and have many local contacts. Most three bedroom apartments (in detached houses overlooking the sea) cost around 60 Euros per night if you book direct. I can provide you with Croatian interpreters if you want but many of the locals speak passable English, Italian and German.
THE WAR FINISHED in 1991 and you will see no trace of it down on the coast.
if you are interested in further comments.
p.s I'm not in the travel business.
