Spending time in very uncommon stops such as Umea, Sundsvall, and Kotka makes this cruise particularly interesting. This route is a special one for the Seven Seas Mariner. In fact, it sails it only once.
The price is the total you pay for a suite, no surprises. What makes this cruise special is that for a limited time you can book a suite for the inside price!
