We were first-time river cruisers and had such a good time that we already have booked another one. We like the more intimate feeling of a longship, especially the open seating at meals. Informative lectures helped us understand more about Russia, and the articles in the daily paper let us know more about the things we were seeing. The tour leaders are exceptionally trained and were able to answer any question from the group.
Viking is well organized for on- and off-boat routines, tour bus numbers and groups, and keeping things moving. Do pay attention to the codes for levels of walking in the itinerary if you have any problems (knees, hips), and ask the tour director or guide before setting off about the distances and restroom availability (one on our bus was on water pills). Staff hands out bottles of water every time you leave the boat for a tour. Excellent!
Do not miss the home visit in Uglich; it was the best stop on the trip. Wonderful homemade vodka, brown bread and dill pickles, followed by apple cake and tea, then a visit to their backyard to see a huge garden with nary a weed in it.
Very comfortable room for two of us. Suitcases fit under the beds (very comfortable beds), closet with a shelf and hangers for clothing. TV had channel choices, but we usually only watched some of the lectures from the lounge. Thick towels, good soaps, shampoo, etc., but a small shower. A bonus is the pull-out laundry line in the shower to hang any hand-washed items to dry. Refrigerator has two bottles of water, always cold.
