I never use Amex because they're the only card that has denied me a chargeback. Basically the hotel runs a nice little scam and Amex enables it. They seem to be very shy about accepting chargebacks to hotels. The scam was that you'd book a cancellable room and the hotel would cancel your booking after they accepted it due to "unavailability of the room" (wtf), then rebook an identical "alternative" room "at the cheapest rate" which happens to be an uncancellable room at $1 less. Why? Because they are impossible to find. No taxi driver can find them. Maybe don't exist. By the time you find this out you can't cancel the room.
