Yes, I know, I was just addressing the fact that on the UK site (per Lawro), you apparently can't change the CC, while on the US site you can. This may be more relevant for Vegas bookings, which typically require a 1-night deposit at the time of booking. On the US site, one can pay that with a non-Platinum card.
