Hello.
In the Booking Calendar Free version possible to activate the single day selection mode or multiple days selection mode (where all days must be selected individually).
If you need to click on first day and then at the last day and have all “middle” days selected automatically, then this feature available in the Booking Calendar Business Small or higher versions. Check more about this feature here: https://wpbookingcalendar.com/overview/#range-days-selection
Watch it in this video guide https://wpbookingcalendar.com/help/booking-calendar-video-range-days-selection/
You can test Booking Calendar live demos at this page https://wpbookingcalendar.com/demo/ to be sure in functionality and do not have misunderstanding.
Kind Regards.
