If the default check-out plus the cleaning time goes past the default check-in, no back-to-back booking fits. See the formula and the three ways to fix it.
You turned on Protect this interval between bookings and, since then, every booking that touches the previous one is refused — on creation, on confirmation, when editing times, on Early and Late requests. The cause is almost always a single one: the property's default times do not fit the cleaning time.
The formula is:
An example that works: check-out at 11:00, 120 minutes of cleaning, check-in at 15:00. The property is ready at 13:00, two hours before check-in.
An example that breaks everything: check-out at 11:00, 300 minutes of cleaning, check-in at 15:00. The property is only ready at 16:00 — one hour after the default check-in. Any guest arriving at the default time on the same day another one left is refused. It is not a booking with a problem: it is the configuration contradicting itself.
The platform runs this formula when you save the property. If it does not fit, a red warning appears above the property list:
The warning does not stop you from saving — a full-day window ("never on the same day") is a legitimate choice, and that is exactly what it describes. It exists so that you know what you just configured.
Do not confuse it with the amber notice "Cleaning protection enabled. Heads-up: 1 pair of upcoming bookings already breaks the window…": that one is about specific bookings that were already packed too tightly, not about the defaults.
Any of the three solves it — pick the one that matches your real operation:
1. Reduce the cleaning time. Under Settings → Properties, edit the property and set Cleaning time to what the preparation actually takes. In the example, 240 minutes end exactly at 15:00 — and the exact minute is allowed.
2. Move the default check-out earlier. Check-out at 10:00 with 300 minutes: ready at 15:00.
3. Move the default check-in later. Check-in at 16:00 with check-out at 11:00 and 300 minutes: ready at 16:00.
Click Save. If the red warning no longer appears, the defaults fit.
If your operation genuinely does not allow a check-in and a check-out on the same day, keep the long cleaning time and know that this is what the protection will enforce: the next guest only comes in the following day.
The cleaning time is the same one that feeds the team's task. Enter the real time — what the team takes from walking in to the property being ready to receive — with neither too much slack nor too little. To understand what the protection blocks and what it does not change, see Cleaning window between bookings.
Cleaning window between bookings
Reserve preparation time after every check-out and stop a new arrival, a time change or an Early/Late request from eating into it.
I can't change the check-out: cleaning has already started
The team is already in the property. Complete or cancel the task under Cleaning before changing the check-out time.
