The positives - the ports were great; the cabin was good, although smaller than comparable ships but had good storage; the steward did a great job; the food was OK, the menu mostly OK in the restaurants; the entertainment very good and fun; activities varied but standard; the disembarkation quick (we could choose when we wanted to leave), cabs waiting - short line; ship was clean except for the Market Cafe (see below).
The negatives - the Market Café floor under the tables/chairs was not cleaned often enough, most of the dishes were not labeled and you had to guess what it was or try to get a response from the limited personnel. Some dishes were displayed in two rows and unless you had long arms you could not get to it without help from personnel. One day the bread was not sliced and guests were ripping off pieces. The milk machines malfunctioned twice - had to get someone to fix them. The cute ship maps they used to have are now a full page black and white sheet. I asked to have a $100 Euro changed into smaller bills and they wanted a commission to do so (not an exchange, just smaller bills). The excursions were very overpriced so we went with a local company in Berlin and St. Petersburg which turned out great. They raised the "service charge/tips" after we booked and room service now costs $7.98 per order! We like to have breakfast in the room so we can get a head start on the day so was very unhappy about this new charge.
I doubt we will take another Norwegian cruise unless it is going places we cannot duplicate on another line.
We booked a night in a hotel the night before and after the cruise - the Savoy. It is centrally located so we could walk to everything we wanted to see. Took the train from the airport and walked about 4 blocks to the hotel. Visited Tivoli Gardens, Rosenborg Castle, Round Tower, Stroget (shopping area), and Amalienborg Palace. All are worthwhile except the Amalienborg Palace. There is not much to it and most displays are glassed in. Purses must go in lockers (1 Euro) unless very small. Strolled through Nyhavn area - very picturesque. Outdoor cafes everywhere.
Took a hop on hop off bus which helped us decide what to see and it was raining. After going the full route went back to the ship for lunch and then it stopped raining so we got back on the bus and stopped at several places. The route back to the ship was different from the first so saw more places.
Fun city, easy to get around without a tour. Just plan what you want to see.
You have to take a city bus, cab or tour to get to town. Buses are reasonable but have to charge tickets - no cash accepted. Again, plan what you want to see, know when to get off the bus and enjoy!
