Reserve half day

Hello.
My client wants to be able to create two reservations per one day. But only for the start and end date of the range. I am using your plugin for booking accommodation and the least count of days to reserve is 3. And I would like to have the possibility to reserve the start day and end day twice. It’s because of changing of the accommodated persons. One person leaves in the morning and the other arrives in the evening. What is the best way to do that and what version of your plugin to use? Thanks.
