I had only positive impressions of the hike with Kuluar to Everest BC in the fall of 2019. We had good accommodations where possible, a meet and greet and a farewell. And the program was interesting, in town and on the track. The first aid kit was well-stocked (and it came in handy) . All the transfers went smoothly.
Yes, the participants had different levels of training. Slowing down on the trail was by no means unfortunate for me, but it was a matter of keeping warm. Fortunately, in our hike it was not critical. I don't think it's possible to predict the pace at which the participants will walk, and I don't think it's the organizer's job. I myself could not promise that I would be equally good at jumping rocks today, tomorrow and in another 15 days).
We had no shortage of attention from our guide, Sasha Pavlov. We have no doubt in his professionalism, - with such a partner though in space, let alone in the mountains.
I send Kuluar a million thanks, I received invaluable impressions from this trip.
