This was our 2nd cruise with Celebrity. Here is what we loved:
1. the ship itself. Beautiful, and clean. We had an inside stateroom, # 9006, and really liked it. I think if you could book 9010 that would be perfect, as it's a little further away from the staff's entrance (and that door closes loudly sometimes). Tons of seating on multiple decks at the pool, including some plush chairs and lounges. The theatre is very nice, as is the dining room (San Marco). We also loved Reflections at the top of the ship. Crush, the martini bar, is cool if you like a loud, club-like atmosphere. We had a martini flight ($12) and this came with a very impressive presentation by the bartender.
2. - the entertainment. We saw one of the typical song/dance shows, and it was pretty good (although that's generally not our type of thing.) One male performer who sung a little opera was especially impressive. Two of the special acts - White Magic and the violinist Greg Scott - were excellent. These were performances we would have gladly paid to see while on land/at home. There was a string trio called Grand Volta that played every night in places like the wine bar or cafe, and they were excellent.
we liked our room. We stayed in a balcony room on our last cruise and that was nice for the view, etc., but this is a fine way to go if you're looking for something less expensive but still comfortable. The bedding was very good, and we are picky about that.
The only reason I'm not giving this full stars is because Sweden is so expensive (currency is the Swedish krona). We had a $75 lunch that would have cost $25 in the U.S. Stockholm is clean, easy to navigate, and beautiful. We visited the Vasa Museum, which was great. We also utilize the Red Line Hop-On/Off boat tour. This is cheaper the the bus offering, and it was really nice to glide along the water. Almost everyone in Sweden speaks good English, so you won't have any trouble getting around here.
There's just nothing special about this port. It was our least favorite on the cruise. We tried to visit 2 churches, but it was Saturday and both were closed for weddings. Helsinki isn't particularly fun or interesting. There are a few places like a National Gallery, a design museum and a Finnish architecture museum, if you're interested in those things. We did enjoy the small but cool Video and Computer game museum, which is free, and within walking distance of the ship.
We really enjoyed Tallinn. Part of it - within about a 15 minute walk of the ship - is a cute medieval town with cobblestone walks, old churches, good restaurants and a relaxed air. We went to the Olde Hansa restaurant, which serves medieval food and beer. Nice experience. This is the least expensive port too. I just wish we had more time there.
Loved Copenhagen, although it's the most expensive city on this itinerary. The people who live there all seem super happy and nice, and were always helpful. This is a very clean, environmentally green city. We walked around a lot and saw the lovely shops and waterways, churches, etc. We also went to Tivoli Gardens and felt like little kids again on the rides, but also loved the lovely gardens and all the dining options. Really fun. We definitely want to return here and stay longer on land.
We stayed in Amsterdam on land for 2 days after the cruise. The public transportation is fantastic. We bought a 2-day tram pass and used it a lot - it was about $12 and we bought it on the tram. We visited the Anne Frank House, Van Gogh Museum and Rijksmuseum. We bought advance tickets to all 3 of these places and this helped us avoid very long lines at the 1st two (no line at the Rijksmuseum). We also took a canal cruise with Blue Line tours and enjoyed that. There are also many small craft beer breweries in Amsterdam that are fun to visit.
