Failed in the area of knowledgeable land guides. Although not Viking personnel, Viking is responsible for the experience. There was one good guide out of seven. High expectations for food; and the food was, at best, average. Failed at ports of call. All but two ports required bus transportation, not walking distance as pictured in the brochures and on-line. Two ports were cement and cinder block manufacturing companies. Two days, our room was without some power. No a/c, no refrigerator, no TV/music, spotty internet. This will sound petty; but you must prepare for this, and we were not. You go through more than 20 locks. Two or three are interesting. The cabin was impossibly small. Evening briefings were painstakingly read, as were the "lectures" on local culture and attractions. Outstanding staff. Can not say enough about the staff. Beautifully appointed boat, two years old. Clean and well maintained. Some of the on-board "local" entertainment was really good. The rating below are based on the overall price of the cruise. It costs a whole lot more; and therefore, the expectations are a whole lot higher.
