I have to say, it was a great deal for me to do this trek in 10 Days. I chose one of the best months (October) for this trek and without a doubt, the trail was super busy. Nevertheless, I thoroughly enjoyed the trail and made it to Kalapatthar (5,550m). I would definitely recommend Langtang trek as all the arrangements were fantastic. My guide, Lhakpa was very supportive, experienced and took really good care of me. I will definitely choose their service again if I ever happen to trek again in Nepal.
