I have been sending queries to Turismo Nuevo Mundo this morning, and much to my surprise, I am being answered by Kenneth Munro who is their employer.
I did a Google for recommendations for this company and found this!
I do think it is a reputable company, but I am not happy that an employee posted this under a user guise.
Last year we booked with local tour operators that arranged everything for us based on private tours. We were in contact with Francesca in Chile. Her email address is email@example.com. She helped us with information of all ports in Chile.
