To amend the check-in and check-out dates, please usecheckInDateLocalized and checkOutDateLocalized with the format YYYY-MM-DD.
In this case, we do not recommend using fields checkIn and checkOut with UTC format (example 2023-01-30T10:00:00+02:00) it might cause timezone and dates discrepancies.
Update check-in and check-out times using plannedArrival and plannedDeparture.
Include ignoreCalendar and ignoreTerms at your own risk. These will ignore any calendar block or listing requirement and may lead to an overbooking or unsuitable booking.
