We are leaving end of May on Serenity from Venice to Greek Isles. I am just now starting to read up on Greece. Does any one have comments or suggestions on planning shore trips either in Venice or the islands? We are not big on beaches as we feel we can go to beaches in the states. But looking for beauty, historical ruins, markets and restaurants etc. Any comments greatly appreciated!!!Also, are jackets required for men every night at dinner on her? I understand one formal night, two semi-formal; semi is what kind of dress for women? Dressy dresses(cocktail style)? I hope so, as I have 3 besides a gown.
