We just returned from our 3rd Tauck trip and in the past we could never say a bad word about them - this trip sure changed that.
The Tauck land portion was up to their usual standards, but unfortunately the Swiss Emerald was certainly not. The staff was very uncaring, and not at all what we expected. Our room wasn't cleaned several times during the cruise and when we complained the response was, in a word, surly.
Service in the restaurant was very poor. Once they took your order you didn't see the staff again until the food was served, and then if there was anything you needed (like a 2nd glass of wine) you had to literally get up and go find someone. Also, the menu was very limited with only two choices of entree's most nights, no salads, and the only appetizer was of their choice.
