I'm using the Booking System plugin for a few days and I see that the plugin adds one more day to each reservation.
Sombody want to book 2 nights, so he fill check in/out fields:
Check-In date - 01.09.2013
Check-Out date - 03.09.2013
In this case the system will add 3-days reservation. In standard hotel booking systems check-out day is departure day so it shouldn't be count into reservation. In this case it should be 2-days reservation.
Is it possible to use proper check in/out dates?
