If someone was planning a holiday where they travelled, stopped to see the sights, stayed overnight & they did the same again each day, what would be the best minimum & maximum milage that they could travel each day to see the most sights?

Minimum milage in one day could of course be "one", depending on how concentrated the sites you wanted to see were... Where do you want to travel? You could travel as far in one day as you feel comfortable with. This is something that tends to be a trial and error, play by the ear kinda thing once youre in the country youre visiting. Things like weather, illness, language, money are all variables that will effect your travels.

Do it on "Easycruise" - you can cover most of the Med this way.

Go back to the boat each night, it sails during the darkness and each morning you've got a new town/country to discover.
