I'm not following what's going on here. I understand that AmEx prohibits DCC, and I carry my SPG card for that reason, even if not planning to stay at any of their properties. But does the AmEx pre-authorization somehow "inoculate" your settlement transaction against DCC when you use a different DCC-vulnerable card to settle up?
