Do you have your accounting software yet? Mindbody has a scheduling feature so you can schedule the room, the class, and the capacity and clients can view it. There’s another one that does the same.
I can send you a scan of an excel printout if you want, but envision this.
Across the top, days of the week – Sun, Mon, Tues, Wed
Studio A – group-ex – and then the class times listed underneath the days of the week, so all the 9:15am classes are on the same horizontal line under the vertical day.
Studio B – spin studio – same thing, it’s just lower on the grid so people can tell it’s in a different room.
Studio C – mind body – same thing, it’s just lower on the grid so people can tall it’s in a different room.
Since you don’t have 3 rooms, all you would need is one set of days across, and one set of times down.
