I would say 6 at the most. We had 5 after we helped up a couple that struggled, they bailed in the morning. They also took the best sleeping spots, while we fixed the next 2 pitches after we basically rescued them and gave them some of our water (it was august and 104 during the day). You could have fit one more at the widest spot where they were. With 5 one of our guys had to sleep on the far end of the ledge that is body width only. If you were going to have more than 6 you could have 1 or 2 get creative and sleep in the haul bag fixed to the anchors on guano ledge!
