The tour was well organized and informative. My driver picked me up on time at the hotel I was staying at, and we were dropped off at the main offices and the tour began promptly. Our guide spoke excellent English, and was very informative about what we saw. The sites were extraordinary, and the meal served was outstanding. Our guide even handled one member of the group who was, to be charitable, very challenging! I felt this was an excellent value for the money. I also found the website to be accessible and easy to manuever around. I will definately look to Viater to see what is available on future trips.
