Go Tibet direct?
Why book thru a Nepal company when you can go thru a Chinese/Tibetan company? You try dealing with a Tibetan company! In general they are not set up to easily answer emails and handle all the details of communicating with you. In addition the quality of trips tends to vary considerably. Because we work very closely with setting up all the trips we have much more uniform quality, especially as we organize for a number of overseas agents too.
