According to my friend recommendation the company Mountain Air Guided Adventures(p.) ltd. in Thamel, kathmandu nepal for the Everest base camp trek 12 days.I only pay the food myself, they organized the room, flight ticket to lukla to kathamndu and ktm. to lukla. They give the prices usd 700 for the document, flight ticket and guide. Anyone can suggest me about this? can i go alone or i need a Guide for that trip?? it would be easy for me if you give some opinion.
