No UK charter airline; TOM / MON / TCX night-stop their crew in SSH unless of a delay or any other cause that would make them run out of operating hours... What made you think they night-stop down route?
Don't know about now, but a couple of years ago TCX MAN crew used to night stop in SSH they operated down on Thur and came back on Sun, or the other way around. Nice hotel on the Red Sea as well...
