I do believe they pulled C&P already.
I need two rooms each at two hotels, Sheraton and Four Points Pudong in May. They both offer C&P for the dates I want. However, once I booked one room, no more C&P offer for that hotel anymore. So, I ended up booking C&P for one room and Points only for the second room.
I find it too much of coincident that I booked the last C&P for both hotels. So, yes, you can book C&P, but you took the last one, they are not releasing anymore C&P at current rates.
