Your biggest difficulty planning a European cruise is narrowing down where you want to go. A Western Mediterranean itinerary usually includes stops in Barcelona and Monaco, as well as ports in Italy. Eastern Mediterranean cruises encompass eastern Italy, Croatia and Greece, and sometimes even Turkey and Israel. A Baltic Sea voyage brings you to Scandinavia and Russia; the Norwegian Fjords carry their own beauty. Don't forget about British Isles cruises, which allow you to visit castles in England, Scotland and London. For sun lovers, it's hard to beat the Canary Islands.
