We all went to bed around 20:00 tonight, to "rest" before starting the summit attempt at midnight.
We had arrived at the Cayambe Hut hike about 15:15, hiked up (still took me 22 minutes, though it felt like 10), and all piled into the bunks. The toilets are on the bottom floor, one set of bunks is on the middle floor, with a second set of bunks on the upper floor. Nominally, where we slept wouldn't matter, as we would be "asleep" for only three hours. Still, I requested the closest bunk to the toilets. The irony of this request was that I slept for the three hours, and Ts was up to use the toilets 3-4 times during the night, much to the heckling of his coworkers.
Juliana woke us at 23:02, with some grumbling from Tr about Ts' night movements, "No one was going to sleep anyway."
I suspect I was the only person who both fell asleep and had a REM cycle.
