How to set maximum occupancy overall
Here's a logic puzzle that I can't solve! Can anyone help?
I have four rooms available, to give maximum options to potential bookers and allow them to choose between twin beds, double, kingsize, superking, family suite etc. Two of my rooms share a bathroom, so as soon as one of those rooms gets booked I close off the other room so that no one has to share a bathroom. However, two single persons travelling together but not wanting to share a bedroom might not mind sharing the bathroom, so I want to keep this option available, which is why I include both those rooms on Booking.com.
Additionally, I want to limit the occupancy overall to six people rather than eight, for legal reasons. Therefore, when two or three rooms get booked for any particular night, I close off the fourth room and this controls the occupancy levels. But if one booker makes a booking for all four rooms at once, at maximum occupancy, I am faced with the prospect of 8 guests (9 if one couple have a child in my family suite). This has happened already and it's a real risk. What is the best solution?
