July 2015 - Serenade of the Seas to Europe - Northern Europe
We chose this specific sailing primarily because of the three-day stay in St. Petersburg, which allowed us to take the full-day excursion to Moscow and still have two days in the port city. Royal Caribbean is not our preferred cruise line, but the ports-of-call, coupled with our pre- and post- hotel stays in Stockholm and Copenhagen (respectively), made this an ideal itinerary to see Scandinavia, the Baltic States, and Russia (day trip to Berlin from Warnemunde was a plus, but be aware that more hours are spent traveling to/from Berlin than in the city itself).
NOTE: U.S. citizens do not need a visa to visit Russia if traveling via cruise ship in port for less than 72 hours. You can only leave the ship without a visa, however, if you are taking an escorted tour (including a day trip to Moscow) booked through RC or a local tour provider.
