In reply to Full moon addict: yes the permits name the guide. With COVID-19 since last year the agencies organising your trip have several extra things to comply with and act on your behalf for the whole trip and not just permit part eg arranging your visa and they must book your quarantine accommodation etc. I was there Dec to mid Jan 2021 and with the upsurge now you can expect this to be the case even through to 2022. So independent isn’t really possible. Also if you are alone is hard to do any of the peaks you mention anyway because of the gear you need to carry and unless you are experienced at altitude it’s not advisable. For my Lobuche trip earlier this year myself and climbing partner/guide and one porter carried the gear between us but it’s a lot if you include fixed ropes, tent, cooking equipment plus own gear. As an add on relating to your other thread: I usually (go each year) take trail shoes, light hiking boots with a bit more ankle support and if snow plus double boots. Always have a porter and if climbing, not trekking, am with my climbing partner/guide. Last time on Mera I wore my Oly Mons triple boots, it can be very cold even November and every couple of years I’ve met people descending and in trouble with frost bite. I was planning another trip for this month but have cancelled it and doubt it’s possible until end year / 2022 now.
