Thanks, Akichow. I forgot to add that part.
The best times I slept on top, it was at the end of a longer backpack trip. On shorter trips, I'd get up and couldn't eat due to AMS, so needed to get down quickly.
Also, I didn't stress how important watching the weather is. You don't want to be up there in a stormy period. It would be exceptionally cold, and possibly miss sunset and sunrise due to cloud cover.
