Let's assume that I have agreed to pay your next hotel bill. Then, after you have stayed, I refuse to pay up even though the hotel has charged your credit card.
According to you would it be OK to dispute the credit card charge? On what grounds?

Wrong analogy. If its booked via PC.com, its a contract with PC. IHG BRG team is part of PC, and you make a new deal with them. Same legal entity. Lex posterior. A later law/agreement replaces an earlier.
