Studio A is booked for a private rehearsal. It's also booked for a 5pm class, because rentals and classes live in two systems that never compare notes. Someone's getting bumped, and they're already stretching.
Instructors have their own schedules. Matching a teacher to a room to a time, without collisions, becomes a puzzle you solve by hand every week.
Renters and students pay differently. Drop-in class, class pack, hourly rental. Keeping the pricing straight across all of it is its own choreography.
