As it happens I have lucked into a 5K Points Break period for a property I need to stay at with several other people. I know the T&Cs have changed that limit such bookings to two at any one property. However, I have been able to book two sets of nights, which will result in four stays at this property. That's twice the recently changed T&Cs which limit PBs to two bookings per member per property. It will be interesting to see what happens. (I have purchased enough PC points to replace these bookings under a new account with someone travelling with me if need be.)

Odd that their systems would not block more than two bookings at any one property.
