This was our third Viking River cruise, although the first one during the summer months. Everything went smoothly. Food and service were great, as was the Viking Longboat. Scenery is not as "rich" as on the Rhine, but the ports were very nice and the winery tours were terrific.
Weather was in the lower 80s, and had one day with light rain - although the region had more rain than normal, so when we got to Lyon, we could not go up river to our last stop because of the bridges. This actually worked out fine since Viking had their first class buses take us to Beaune - our last tour stop, and then we were able to go back and stay in Lyon on our last night - which was where we flew out of the next day - so got to sleep in a little longer.
Highly recommend the five minute walk to the castle in Tarascon in the afternoon instead of going back into Arles for shopping, Get a card for the Viking reception for a discount on the castle tour.
Stayed on the "bottom" level. Quiet, and didn't miss having a balcony.
