Hi all, here my opinion/suggestion
In order to avoid gaps between guests, it will be good if we had the possibility to add a close to arrival for a day (maybe by 1 click on the calendar on that day).
e.g. if my guest is checking out on Friday 3rd of August, i would like to add a "close to arrive" on the Sunday 5th to avoid guest arriving on that day and that my Saturday 4th August will be empty. You already have a kind of similar tool "only arrival on ......" but if you have many days along the year is quite complicated to have some many special restrictions.
Close to departure: guest will not be able to depart on the selected day (maybe by 1 click on the calendar on that day). Will also help to optimaze the reservations/stays avoiding dificult gaps between reservations.
