"If Grégoire will provide the twenty hours of course offered from Monday to Thursday,"
So I guess that gives us a pretty good idea of what their hours will be; 4 days a week (Mon - Thurs) and I think I saw some mention before of 5:30 or 5:45 pm. Five hours a night for 4 days; not a bad work load. Gives Greg time to go up to his parents school every now and then.
The only bad thing I saw about the place and I think it might have been mentioned earlier is there doesn't look to be a whole lot of parking right by the studio, but maybe where they open late, some of those other businesses will be closed by then and there is what looks to be a shopping center a couple of blocks away.
Edit:
Looks like we know who the mystery guest was.......
