We chose the Serenade of the Seas because of the port of calls. We sailed from Copenhagen to Stockholm, Estonia, St. Petersburg, and Helsinki.
Overall we had a real nice time. The ship is a little older but has that throwback elegance from the bigger ships. It is easy to get around. The staff was very friendly and the rooms were nice and clean.
We did shore excursion at every port of call. The first port of call was Stockholm and we chose the bus tour. The staff was late getting us on to the bus , which in turn cut into our tour time. So we were rushed in Stockholm and unable to do a little shopping for gifts. We were giving the option of staying back and taken a cab to the boat. However at that time we were unsure if we would make it back on time to the boat. Plus we spent money on the excursion and didn't feel the need to spend more money on a cab that might take the long way back to the boat.
