Scandinavia is a European destination for both seasoned cruisers and for first-timers who have already experienced other areas of Europe by land. Stress to your clients that they will be paying for their cruise in U.S. dollars, which makes a European cruise one of the best vacation values going right now. 
Scandinavia is positioning itself as a formidable cruise destination. Just this past month, Stockholm not only opened up a new cruise season, it opened a new cruise terminal. The Stockholm Cruise Center Frihamnen will receive a record-setting 265 ships in 2008.
The window to take a Scandinavia cruise is from May through September, with the high months being July and August.
If your clients are looking to really get an up-close, in-depth look at the extremely varied geography of Scandinavia, they might enjoy a cruise line with smaller ships, such as Hurtigruten. If your clients are more interested in what is on land, recommend a cruise line with larger ships, like Holland America Line.
Here is a look at which cruise lines offer Scandinavia cruises and the itineraries they operate. The 2008 season kicked off in May, so below is dedicated only to 2009 details. Most cruise lines are already accepting bookings for next season.
