So you can book the base room (cash or points), and apply a club certificate to get a room with an occupancy of 3. You would have been entitled to the upgrade if it was available at check-in, but sometimes you don't want to take that risk.
Like granting Glob benefits to more than 1 room, getting a club level room is not part of the T&Cs. The award gives you club access and says nothing about rooms.
