Room reservation

Hi, I need some tips on how I could implement the following.
I want to specify dates in Kirby for a room when it is available. So classic like on every booking page.
A page is created for each room, there I can set the availability via a datepicker. But the big question now would be, how can I change the availability when a customer has booked a room? Anyone have any ideas?

Well, basically you would update the page with the booked dates (and probably times). But I’m not really sure what you are expecting as answer.
