I agree. I review the exchange rates in advance of international trips to gauge prices. In this case I didn't have a complaint since the price I paid in USD was the quoted price at booking in USD and my ~$30 in incidental food and beverage also used the hotel's reference exchange rate that was more generous than the official rate.

I do look out for what you're describing, however, where hotels will use a reference rate in some familiar currency, such as USD or EUR, but will convert at their own, unfavorable exchange rate to the local currency for the official bill and sometimes try to DCC on top of that.

Yes, I'd recommend everyone have a debit card that reimburses ATM operator fees while traveling. While DCC should be universally avoidable as long as ATM operators are following the rules, some ATM operators charge almost usurious rates for using their machines. There's also the practice of adding a fee only if one declines DCC, as demonstrated in .
