I do mean Cossacks. We do a lot of land travel in conjunction with cruises and we're spending 7 weeks in Europe starting in Iceland and ending with Cappadoccia and Amsterdam after Cossacks. We also have an Adriatic cruise on Azamara before Cossacks. So much to see and so little time to see it.
BTW, Iceland has gone non-smoking inside buildings, including restaurants and bars. Outside seating (where smoking is allowed) is quite popular on sunny days but there is usually a breeze to keep smoke away.
