We actually started our cruise on the Star in New Orleans, La., USA doing the Transatlantic (see prior review) and then stayed on at Copenhagen to do the Baltic roundtrip without changing staterooms, etc. It was a great was to get to Copenhagen. Easy to adjust to the changing time zones and cheaper than flying.
The transatlantic trip was generally good to very good in our estimation. A significant portion of the guests on board changed at Copenhagen and the ship picked up a large "GROUP TOUR" of Asian decent people. That group changed the enjoyment factor by quite a lot. They were as a group very pushy, inconsiderate of others and loud in every area. They basically took over the Versailles Dining Room by making large group reservations making it difficult to meet the needs of other cruisers. We found some ways to mostly avoid them after the first couple of days and that helped, but it did negatively affect the enjoyment of most on the cruise.
Our stateroom attendant changed at Copenhagen and even though the one we had on the transatlantic had been very competent, the new one was equally good with a much more engaging personality.
We did "Off ship" tours that had been pre-arranged before we left home. It turned out to be an excellent choice. We had contacted Alla Tours based in St. Petersburg and set up a "Customized" 5 City Comfort Tour package that worked to deal with my spouse's limited abilty to walk/climb stairs, etc. Alla prepared a package at an excellent price point (especially related to NCL pricing) that included a wheelchair at the Hermitage at SPB, sit down lunches/breaks both days in SPB and a private car for two with guide in Tallinn. All of the guides were good to excellent. We did a Warnemeunde/Rostock tour in Germany and had a Mexican guide - Pepe was excellent and there were only 6 of us on the tour. Alexandra was our guide in SPB, she was also excellent.
By the time we were doing the Baltic portion of the cruise, we had been on this ship for 16 days. We were already pleased with the food, the crew personality and mostly everything else. The main negative was the large tour group of Asians that put a damper on it by their level of aggressiveness and degree of non-consideration of other cruise passengers.
We enjoyed the cruise and had a very good experience. There are a few things we prefer in general on Royal Caribbean to NCL, but we think we had a very good value for our money overall.
