Based on a wonderful Rhine cruise on Viking last year, we booked the Portraits of Southern France river cruise for this year. What a mistake. We arrived in France at the tail end of the European heat wave. The temperature was in the upper 90s. The air conditioning on the ship was not functioning properly and the cabins/restaurant areas were very warm to the point of being uncomfortable. We were never addressed by the Captain to explain the problem. Various crew members gave different reasons. It was obvious that there had been some instruction not to comment to guests. I felt so sorry for the restaurant servers who had to work so hard in the heat. The problem was finally fixed on Day 5 of the trip. Thank goodness the weather broke and became cooler. On the evening before the problem was fixed, however, our cabin was 81 degrees. We could not open our doors because there was an invasion of spiders. The ship had to call for pest extermination. The we could not use the veranda since it had been sprayed with pesticide. The other not so great part was dinner in the restaurant. Again, some offerings were hit and miss. The serving portions were also very small. There was nothing available for snacks for that 9PM hunger attack. We were fortunate that we had a suite that was supplied with fruit. The ports of call were mostly great. Lyon was fantastic. The small French villages and cities were beautiful. We especially enjoyed our excursion to Beaune.
