My husband and I have been on many cruises, but this was our first river cruise. We were really looking forward to the experience of sitting on the top deck (or our own balcony which we paid extra for) and watching the French countryside and drinking some good French Wine. Our first day was just that - a beautiful views from the sun deck with a good glass of wine. On our second day in Lyon after a nice city tour, we were informed during our daily review that there was a problem with a critical part of the ship and our departure would be delayed. We were disappointed but were expecting the delay to be a half a day at most. This delay became 3 days. The cities and towns that we were supposed to be crusing to became bus tours of over 2 hours each direction and terrible rush hour traffic on return to Lyon. (where we were parked for 4 days with a view of a stone wall and a bike path).
Once the part was replaced, we only cruised at night when we were sleeping. We never had the use of our balcony for river cruising. To top it off, the cruise before ours (on another ship) had the norovirus and those passengers were allowed to board our ship. We had no coffee bar, no access to public restrooms, no salt and pepper, or sugar and cream on the tables, no bar snacks. We had to be served at the buffet breakfast (3 or 4 people serving several hundred passengers). We were not offered any renumeration for our inconvenience - not even a token bottle of champagne. The basic attitude was "it is out of our control - not our fault".
Since we paid significantly more for a river cruise than we would have for a land tour (and a "hotel room" on the ship that was significantly smaller than a normal hotel room) we asked Viking for a partial refund. Our request was refused with an offer for a discount on a future cruise. We will NOT be taking another Viking Cruise.
The cabin was an acceptable size (but not that large). Shower was a small stall with glass doors. Balcony was a good size with a small table and a glass front.
Tour guide was very knowledgeable and informed. Saw all of the highlights of the city and had some free time on our own.
