Fair-use rules, set once.
Pick the HOA fair-use preset and residents get an advance booking window, daily and weekly limits, a cap on prime-time hours and a cancellation lockout. Limits can apply per person and per household, so one family cannot take every evening.
Residents book themselves.
Share a join code with residents, or require approval so only verified homeowners get in. They book from any phone or computer with no app to install, and get email confirmations, plus text reminders if they opt in.
Everyone can see the courts.
A public schedule shows what is booked and what is open, with names hidden unless you choose to show them. Put the kiosk display on a screen by the courts and players can check before they walk over.
