I just got back from the RIO JW Marriott. I was quoted $269/Night US. When I checked in, the rate indicated $269/Night. When I checked out, they used a 1.8 exchange rate to charge me in the local currency which was 485 Real/Night. The 1.8 is way above the exchange rate. The hotel does not do currency exchange, but they have a local company that has a booth in the lobby. They were offering a 1.55 exchange.

At the end, I was being charged about $305/night because my credit card was only giving me a 1.59 rate.

If your reservation shows a US rate, shouldn't the exchange cover this rate? What is everyone else's experience?
