Where it usually breaks
And how to keep it from happening.
- Conflicting nights. Another confirmed stay on the same unit blocks the request even if the unit looks available today.
- Party exceeds capacity. Compare guest count with the booked unit before confirming; leave an invalid request unchanged.
- Arrival without a clear charge. Keep the checked-in reservation, occupied unit and authorized folio item linked. Payment status does not change merely because the guest arrives.
