It looks like the newbies have had their photos added to the Sleep No More homepage. There are seven total it appears (Chelsey NG and Assaf Salhov are also added). Seven seems like a lot though we did just have six leave (seven if you count David Botana). What is the biggest turnover you remember? This cycle seems to have more than previous ones I remember.
Yes, this is the largest change that I remember, at least in terms of number of incoming folks. Adding six to the total number of the cast (6 gone, 12 new) might signal some structural changes in the way the cast is scheduled. I have no specific knowledge of what is motivating this change–but safety seems a solid guess. The show can be a brutal grind, and we see this in the number of injuries and frequency of injured cast. One hopes that having a few more people in the schedule might alleviate some of the physical strain.
