My last real chance to do this due to age and health - and I picked a winner!
The crew on this trip was outstanding. They all memorized my name within the first day. Made me feel welcome at every turn. The excursions were outstanding. One of the reasons was that each of us was provided a personal receiver so we could hear the tour guide withount crowding up to the front. Didn't feel hurried or stressed to hear his her descriptions.
All of the guides lived in the areas visited on each stop, including the bus drivers (where required). They were all very knowledgeable and courteous.
Excellent facility. The only suggestion I have is to get a price break when only one passenger for a state room. My wife is much too ill to travel.
