Greece has always been on my radar for a winter break, (Peloponnese) wouldn't like it in mid summer as temperature way to high for Barb n Me, early spring/autumn sounds good.
It would be a 5000mile round trip and careful planning of routes and ferries would be required, I am sure Brian (Lisa n Brian) have some very useful information, I did Greece many times when working but we are talking 20/30yrs ago and used routes then that one would not use these days.
Would love to have a motor-homers trip there, so over to you Frank start the planning for 2014.
