A room, a table, a sauna, a hot-stone set: anything a booking needs to hold. Palm assigns it, refuses the fourth booking when you have three rooms, and never puts a couple in the solo suite.

Every appointment gets a room that fits the service, or it isn't offered.
Three rooms, three appointments at once. Not a hope, a refusal.
A sauna, a float tank, a salt room: a resource that is also a bookable service, out of the same calendar.
A couples suite gets turned once after the couple, not once per therapist.
"Couples can't go in the Solo Suite." "I want to book the infrared sauna." Set.
A booking needs a therapist, a time, and somewhere to happen. Palm treats the third one as seriously as the first two.
Deep tissue anywhere; couples only in a couples suite; hot stone only where the warmer is.
Turnover time per room, so the next booking can't start while the last is being cleaned.
A room that seats twelve for a sound bath is one booking with twelve spots, not twelve bookings.

The first thing built this way, from a solo therapist's Facebook post. A resource is a room plus the service that books it, and neither half is offered for anything else.
A sauna booking must never be offered a massage room, and a massage must never be offered the sauna.
A 4:00 sauna beside a massage running to 4:30, on the same calendar.
Deposits, reminders, and the front desk treat it as a service.
Yes. Rooms belong to the studio; the booking picks one that fits the service and is free.
Then two appointments never overlap. Say so and Palm caps the day at one at a time.
No; you can. Clients pick a service and a time, Palm picks the room by your rules.
Yes. One hot-stone warmer means one hot-stone booking at a time, whichever room it's in.
Finally, a scheduler that runs your calendar the way you would.
