Double bookings are the most common and most painful mistake in holiday rentals: two guests book the same dates through different channels. The result is cancellations, bad reviews and platform penalties.
Why double bookings happen
If you rent across several platforms (Airbnb, Booking.com, Vrbo and your own site), you quickly end up maintaining several separate calendars. The moment a booking is not immediately reflected everywhere, a gap opens — and that is exactly when someone books twice.
The fix: one central calendar via iCal
The open iCal standard lets calendars sync automatically between platforms. In practice:
- Sync every channel to one central calendar (import and export).
- Mind the sync lag: platforms refresh iCal feeds only every few hours — last-minute bookings remain a small residual risk.
- Block dates you do not want to rent (own use) manually in the central calendar.
