Hi,
I suggest to add a new column in the departure report for next arrival date, cause it will help to see which property have to be cleaned first. In my company, those apartments with check-out and checkin same day are our priority for cleanings, after they are cleaned we start to clean those apartments that have next arrival in next days.
Also when you check only departures in a report, the report comes with arrivals dates also and that columns are useless and confusing when you have many departures to follow... so better to erase those columns and only let what i check (only departures, no arrivals, no stayings).
