I asked Booking.com to cut off bookings at 7.pm and Expedia.com the same at 7.30pm nightly.( we close the door at 7.30pm) This is working so far. Booking.com can only cease bookings on the hour not the half hour. The phone numbers I use for Expedia.com are 1800 789 756 & 02 8031 8467 it is an automated answering service and it has been usefull for me at times.
