We were on the same cruise and really enjoyed it as well.
We were in an oceanview cabin on deck 4, which is a great location when getting on and off the ship.
Our only complaint was with the diamond lounge and its concierge. The room is small, an area that they created by blocking off an area of the Viking Crown Lounge, and didn't have nearly enough seating for all of the people who chose to use it. We arrived one night and there were no seats. When I mentioned it to the concierge (Francisco) he didn't even know as he'd been at his desk on the computer with his back to the room. I asked if he could open the door to the VKL, but he said he couldn't, it was company policy. He then walked us out of the room and blocked the entrance. Later in the week we saw him open the door to the VKL for another group. He was very disappointing and nothing like any of the other diamond concierges we have had before.
We had a 5 night specialty restaurant package and ate twice each in Chops and Izumi and once in Giovanni's. All three restaurants were excellent, and we enjoyed them as a break from the MDR. We had a table for 2 for late seating and were seated at the very back of the room, where there were several 2 tops. Our servers were excellent and we found the food to be very good.
There were a lot of kids on board but we found most of them to be well behaved and supervised. As this is a very port-intensive cruise, I think they were always pretty busy.
We thought the orchestra was exceptionally good, the singers and dancers not nearly as good as we've seen (and that's being polite!), the headliners fabulous (particularly Pete Matthews and Beatle Maniacs), and Cruise Director Mike outstanding!
We used Best Guides in St. Petersburg and were fortunate enough to share our tour with a wonderful family of 5. Our guide, Olga, was great at providing us with information and getting us through any crowds easily. Our tour, St. Petersburg Grand, included lunch at sit down restaurants both days and they were great opportunities to try Russian food.
In Helsinki and Copenhagen we took local food tours, which provided us with a walking tour of each city along with nice food tastes. We walked around on our own in Tallinn and Skagen, and took the HOHO boat in Stockholm to the VASA and ABBA museums, then walked around the old town and ate in a restaurant on the square.
This was our first visit to Amsterdam and we absolutely loved it. We had the same experience as Sue with the train tickets- we thought it was because our credit cards didn't have pins to go with the chips. We took a train out to Zaanse Schans to see the windmills, and did a food tour and red light district tour, as well as the Anne Frank house.
