Eleven at night, one room short
A couple arrives off a late train. The hotel is full. The PMS shows their booking, from an OTA, made yesterday afternoon. It also shows every double taken. Somewhere, one room was sold twice. The night porter rings round other hotels, finds a room in a chain hotel across town, pays for the taxi, and apologises. The couple are polite but it is the end of their evening and the start of a review.
The next morning the front office manager tries to work out how it happened. The channel manager log shows availability was updated. The OTA shows the booking came in a few minutes later. Or perhaps it was the room that went out of order at five. Or the group block that was partly released. Nobody is sure.
Why unplanned overbookings happen
Availability for an independent hotel lives in the PMS and is pushed out through the channel manager to the OTAs and the booking engine. Most of the time this works. Overbookings come from the edges.
- A room goes out of order and the change is not pushed to channels immediately.
- Room types are mapped differently in each channel, so selling one type uses up another.
- Allotments given to wholesalers or tour operators are not deducted properly.
- Group blocks are released in the PMS but the channel manager is not updated.
- Manual bookings taken by phone at the same moment as an OTA booking.
- Connection problems delay updates at busy times.
Some hotels overbook deliberately against expected no-shows. That is a revenue decision. What hurts is overbooking nobody decided to do.
What a walked guest costs
The direct cost is the alternative room, the taxi and whatever gesture you offer. The bigger cost is the guest's experience at the worst time of day, the review it produces, and the booking that might have been repeated and will not be. If the booking came through an OTA, the OTA may have its own process for relocations that adds to the cost and effort.
Staff feel it too. Walking a guest is one of the hardest jobs on a night shift, and doing it without warning is worse.
How we build an overbooking check
- The check reads room inventory by type and date from your PMS, including out-of-order rooms, group blocks and allotments.
- It reads what each channel is currently selling from the channel manager, and bookings as they arrive.
- For each date and room type, it compares rooms available with rooms sold plus rooms still open on channels.
- Any date and room type where sold exceeds available is flagged immediately, with the bookings involved, so the problem is seen days ahead rather than at midnight.
- Dates getting close to sold out are watched more closely, and mismatches between the PMS and channels are flagged even before they cause an overbooking.
- Each incident is logged with the likely cause, such as an out-of-order change, a mapping, a late release, so the root cause can be fixed.
| Cause found | What the check shows | Usual fix |
|---|---|---|
| Out-of-order room not pushed | PMS inventory lower than channel inventory | Push update, check the process |
| Room type mapping | One channel selling a type you do not have | Correct mapping in channel manager |
| Wholesale allotment not deducted | Sold count higher than inventory | Adjust allotment setup |
| Simultaneous phone and OTA booking | Two bookings for the last room minutes apart | Move one guest in advance |
When an overbooking is found days ahead, you can move a guest to another room type, contact them in advance, or arrange a nearby room calmly, rather than at the desk at midnight.
A sold-out night that stays under control
Two days before a sold-out Saturday, the check flags one extra double sold. The cause is an out-of-order room whose change was not pushed to one OTA. The front office manager offers one of the guests an upgrade to a suite that was still free. On Saturday night, everyone gets a room.
Over a few months, the incident log shows which causes keep coming back, and the fixes are made at the source. The night porter stops dreading the last check-in on a full night.
Is your hotel overselling by accident?
- You have walked guests when you did not mean to overbook.
- It is hard to work out afterwards how an overbooking happened.
- Out-of-order rooms and group releases are handled by hand.
- You sell through several OTAs, a booking engine and wholesalers.
- Overbookings are usually discovered at check-in.
