We were eager to visit Russia and the river cruise seemed to be the simplest method of doing so.
We had to request the Letter of Invitation from Viking, because they did not send it automatically. About 10 days after the emailed request, we received the documents by email, written entirely in Russian and immediately applied for the Visas. We paid ILS an additional fee to transfer the information from the letter to the application. I hand delivered my Visa application, while my companion sent hers by express mail, which was returned to her the day prior to her departure.
The Viking ships are docked about an hour's drive from Moscow center and traffic is very heavy. We spent much time on the bus, trapped in gridlock. Visits to attractions were shortened or skipped entirely, due to the time required to travel to them. Information about the following day's tours was provided in the evening, so it was difficult to make alternative arrangements at the last minute if we were not interested in those available. On one day, there were morning, afternoon, and evening tours, which meant a minimum of 6 hours on the bus, travelling between the boat and the city. Another day, we were provided with a snack when we left in early morning and returned to the boat at 9 pm for dinner; there was not sufficient time in one place during the day to enable us to eat in a restaurant.
The single beds were 30 inches wide and my companion awoke frequently with a fear of falling out of bed. The room is very small, with little storage, but our suitcases fit under the beds. There is one small chair and a small stool in addition. The washroom is quite small, particularly the shower stall. There was ample hot water. There is a fridge in the room. This is a small room, but the only one which offers a view in front of the ship. The sun deck has an indoor bar and outdoor seating area at the stern. These are both too small to accommodate all of the guests.
