Do you get more bonu points if you book more than 1 room?

For instance, if I book 2 rooms at a hotel for 3 nights, the other room being for another person (under my PC number), would I be able to claim the Stay 3 Receive 3,000 points bonus, as technically I'd have 6 nights booked with them?

Anyone have any ideas or recent results from this type of stay?
