Just back from a Tucan travel from Lima to La Paz. I am writing this to,let others over 65 that this isn't for them. Shoddy accommodation - jungle accommodation was good - couldn't use shower in La Paz - staying on Lake Titcaca with locals puts one out of comfort zone. Not enough detail in itinerary - nothing about a 7 hour and 10 hour public bus ride. Tour guides should ensure that one has lunch before 3.00pm. Enjoyed Machu Puchu due to a wonderful guide Margot. As I suffered breathlessness she was a great help. For those wanting a little more comfort got to other travel guides. Denise - August 4th 2014
