Make access explicit
Define which teams can see and reserve each room. Document exceptions, such as an operator booking on behalf of a team.
Set fair-use boundaries
Booking horizons and limits can prevent one audience from taking every desirable time. Tell users why a slot is unavailable or ineligible.
Keep commercial processes separate
Room reservations, paid guest bookings, and tenant billing are different workflows. Confirm which system owns each before promising an end-to-end process.
