Cleaners often charge extra for same day turn overs, but that extra charge isn’t something easy to pass to guests. What I have done at times when I suspect one of these might happen next to an existing booking is to go to the calendar and manually add that additional fee to the rate for nights adjacent to existing bookings.
Could Hospitable add a fee that only applies when a new booking produces a same day turn over (e.g. the new booking starts in the same day when an existing booking ends, or it ends in the same day when another booking starts)? Notice that the fee would need to be applied per turn over that the new booking creates, which could be 2 when a new booking is adjacent to existing bookings on both start and end dates.
