We went with a group of 18 but had a core group. I am a very big Viking fan and this was our third cruise. The staff and service on the ship were excellent and the new ship designs are definately more effective than the older ships allowing everyone to fit into the lounge area for breifings and other presentations. Also, the cabins seem a bit larger and we felt there was very adequate room.
The food was good but wouldn't describe it as great however one excellent thing Viking has done is to serve a limited lunch in the lounge area which is a nice break from the more formal dining room. It also allows you to enjoy the views and outdoors better. They also did a very good job offering a variety of local cuisines.
There are a couple things were a bit dissapointed in. One of these was the quality of the ongoing on ship entertainment. While the Cruise Director and the games / evening events he organized were good, the resident pianest / singer could have been more entertaining and engaging.
Better than adequate. Loved having a balcony. Would like to have a little more room to wash and dry laundry during the trip.
