I left Lucky a detailed comment on his post about DCC. My favorite parts of the reply from the manager that include the coaching language from Travelex. You're right to include the exchange rate links for both Visa and MC. A lot of people like to use Xe or similar sites, but the only official source (down to the cent) is the rate from either Visa or MC. Using Xe or Google provides a rate that's close but not exact and gives issuers and others some excuses. In contrast, using the official Visa and MC rates for the posting date of the transaction gives you the exact charge that should have appeared on your card's statement.

Speaking of which, klashn and I just checked into the SkyCity Marriott. I followed my own advice and checked in with the AmEx Platinum for the preauthorization. I'll check out tomorrow with my Chase Marriott Visa, specify HKD, and request a courtesy copy. I'll use the percysmith technique and state I need the original receipt and courtesy copy for category bonuses. I'll repeat what I did one year ago. I will report when I get back stateside later in the week.

My sister-in-law is also visiting, so I can be on the lookout for more DCC in the US.
