I feel like an idiot for not asking for the terminal before handing over my credit card. I'm in Paris and I see no evidence that the incidental and room rate is being charged in USD. Obviously, I want to be charged in Euros to get the best possible rate. The receipt shows a pre-authorization of €266.63. I'm assuming no DCC? At check out, I'm guessing just the room rate will be dedicated from the pre-authorization and the rest will be refunded back to my card?
