Hi John Doe,
You do not necessarily need to worry about what shift she is on. As long as she knows in advance that you are coming, then she can try to plan accordingly. Also, you could try emailing her and asking her if 10pm on that certain day is alright with her. That way you can converse through email first and if there is a conflicting problem with 10pm the two of you can work around it. Hope you have fun at the Ranch 🙂
