for the "Three Passes" (Kongma La, Cho La, Renjo La) trek. We already knew what itinerary we wanted but we were looking for assistance with permits, flights (helicopters; we didn't feel like dealing with going to Ramechhap for the fixed wing flight to Lukla), lining up a porter, and making reservations in advance at the lodges (we were trekking in Nov and, while not quite peak season, it was crowded and especially in places like Lobuche, we were really glad we had reservations). EH set us up with a wonderful guy, Chepa, who was ridiculously fast and just a pleasure to trek with (we'd all been up in the Khumbu numerous times and didn't need a guide). All the lodge bookings had been made as we'd been told, though I'd suggest doing some research in advance and telling EH if you have a particular lodge you want to stay in at each village (and what kind of room - standard, attached bath, etc). We didn't specify any particular lodges and, while the ones they selected for us were mostly good, in two cases they'd booked us into somewhat run-down lodges and there were definitely better options available (in Deboche, I'd recommend the Rivendell Lodge, and in Gokyo, either the Thanka Inn or the Himalayan Eco-Lodge). EH did a great job with arranging the helicopters and were suitably flexible with other aspects of the trip (for example, we ended up coming back to Kathmandu a day early and it was no dramas). Navin and the rest of the EH staff were professional, competent, charged very fair prices (we shopped around), and overall did a great job of arranging our trip. I can recommend them without any hesitation.
