There are two instructors in his room, so definitely them.

There are two instructors in the other room that I see now and again, so I'm thinking definitely not them.

Then there's like a manager that handles all communication etc. So I was thinking yes on her- but should it be the same amount as the two instructors?

Also, do you tip the director who is the owner?

Any amount suggestions? He goes 3x a week but this woman also owns the nursery he'll be attending, plus I have a ds2 only a year behind him- so I'm not looking to be cheap.
