Destination Unlimited was a God send when we were anxious about finding the right agent, given all the stories we heard about dubious agents in Nepal. Ashok was super responsive in helping us plan the trip, highly flexible as our plans evolved, including last minute changes they required us to change the trek.
His staff including both the guides (Ganga and Ambhir) and the porters were extremely helpful and took care of us all along. This is very important in Nepal when you are on a trek because the hotels have an interesting model where your guide essentially serves you during lunch or dinner, or if you need any other help during your stay.
We were two families with a kid each - do having two guides was extremely helpful because at least one of them needed support during the trek.
Highly recommend Destination Unlimited.
