Hi Chris
Greece is a bit far for towing, but we are going to Lac de Cazeau, Sanguinet for two weeks in August.

We have a number of family friends all at the same location, so it is here that I plan to get Nicky onto the boat - and not before. Two weeks on somewhat sheltered waters with a large quantity of superb sandy beaches and lakeside restaurants with pontoons should do the trick!
The lake is 5600 hectares. Put 'Lac de Cazeau' in Google Images.
