Use a bounded unavailable interval
Synthetic blackout closes room R-B from 10:00 inclusive to 12:00 exclusive. A booking is affected if it uses that room during any part of the interval. New bookings are blocked; existing ones enter review, retaining their records and session allocations until an outcome is chosen. This is not a room-capacity calculation.
| Booking | Room / time | Impact | Next action |
|---|---|---|---|
| B-B1 | R-B / 09:30–10:30 | Affected | Offer another room or cancel |
| B-B2 | R-B / 11:00–12:00 | Affected | Review relocation |
| B-B3 | R-B / 12:00–13:00 | Outside blackout | Keep booking |
Resolve each affected booking
- Record room, blackout boundary and reason before blocking new availability.
- Build an affected-booking list with entitlement and communication status.
- Record accepted relocation or operator cancellation for each booking.
A proposed alternate room does not clear review until its suitability and the required customer choice are resolved.
Which bookings need action, and why does B-B3 remain?
Show the worked answer
B-B1 and B-B2 need review. B-B3 starts at the exclusive end boundary, so it uses no blackout time.
Track unresolved outcomes rather than deleting bookings to make availability appear correct.
