We spent north of $10k USD on a cruise of the Baltic Sea with a lot of ports, including 2 days in St. Petersburg and before and after cruise visits to other countries. Glorious.

I don't fish. The places we found most interesting were Ireland and Denmark, so we're going on extended trips just for those places. Ireland was full of history, some of it recent. Denmark seemed more like they embraced the future, and Copenhagen was large and modern, without going crazy like Seattle.
