Was there a master bill? If so, none of the hotel guests earn anything. You also wouldn't earn anything for the stay if someone else paid for it, such as the organization sponsoring the meeting.
OTOH, if you paid for your room with your own credit card, it should earn unless the contract says otherwise.
