Still pondering choices for 9/06. The Cloud goes from Copenhagen to Stockholm for 7 days. The Whisper departs the same day from Copenhagen and goes to Amsterdam for 9 days. The price is only slightly higher. The second itinerary includes Rostock and transits through the Kiel canal omitting Stockholm. It also includes 3 sea days(rather than 1). Thanks to all of you experienced cruisers for any advice! Julie in Denver
