This was our third cruise with Viking...and each one has been superb. Excellent accommodations, fantastic food, diverse and entertaining places to go, see and do.
Viking caters to adult travelers... so don't expect to see young children. There have been several teens on our trips who were well educated and well spoken. We have enjoyed their company.
My wife has limited ability to walk, so we travel with a light-weight transporter chair. It was very easy to use the chair on board. The crew assisted every time in getting on and off the ship. The chair was difficult, but possible, in some locations because of cobble stone pavement.
Roomy with a good view and a pleasant veranda
