Spots per machine
If your reformer room has 6 machines, the class takes 6 bookings and closes itself. The mat room can have its own capacity.
Reformer and mat with one pack
With credits, a mat class costs 1 and a reformer class costs 2 (or whatever you decide). Clients use the same pack for everything.
1 credit = 1 class
Clients buy credits (one at a time, in a pack or with their membership) and each class uses as many as you decide. So one pack works for all your classes.
A mat class costs 1 credit; a reformer class, 2.
Privates and small groups
Private or semi-private sessions are classes with a small capacity and their own price in credits.
Waitlists for the classes that fill up
Early reformer classes fill up: if someone cancels, the spot goes to the next person on the list with a notification.
