Our tour director referred to our trip as the cruise from hell, so i am not exaggerating. The customer service aspects of how Viking dealt with a catastrophic A/C failure on its ship during a heatwave was telling. First deny the problem, than deflect the blame for the problem, then distract the passengers from the problem. Fixing the problem should have come first. An apology and acknowledgement would have gone a long way, too.
First the Good: (1) The fellow travelers were great -- every made the best of a difficult situation. (2) The ships staff and crew - they were troopers and had to put up with the same discomfort that the passengers did, and they did so with charm and good humor. (3) the Itinerary - the towns we visited were well chosen, and the local guides were excellent. (4) The ship (Viking Delling) had everything one would want on a river cruise ship -- the staterooms are well designed, the bathroom is large as far as cruise ships go, and the showers were great (hot water and good pressure). The lounges and common areas were plentiful and well designed. (5) The chef was accommodating to the vegetarians and gluten-free diners in our group.
The Mediocre: (1) the food was so-so. It was plentiful, but nothing to write home about. Avoid the soups at all costs. Their version of clam chowder and lobster bisque were watery soups--not a chowder or a bisque. (2) the women in our group complained there was not enough time to shop in the towns we visited. (3) The on board entertainment -- it was basically a Ricky Martin look alike, with a nice voice, at the piano, doing English as a Second Language Karaoke each night in the lounge.
Well designed cabin. Lots of closet and shelf space. Nice TV and sound system. Great bathroom and shower. If the A/C had worked and I wasn't sweating in bed as I slept, it would have been perfect.
