I have reserved and paid for a nine-day cruise to the Baltic in May 2017 with a stay of 3 extra days in Copenhagen. We also visit Warmemünde, Germany (I do not know anything about the city - 2 1/2 hours from Berlin by train, one way,) Tallinn, Estonia (probably the prettiest medieval city in Europe,) St. Petersburg (2 days,) Helsinki, and Stockholm. I have never been to any of those cities; my wife has. I always wanted to visit the statue of the Little Mermaid in Copenhagen :) . I'm kidding. I know it is very insignificant, but world famous :)
I also reserved a 7-day cruise to Alaska for September 2017.
And for 2019 (more Mayan ruins)
