I have occasion to travel frequently to the former Warsaw Pact nations, and find that the hotels there (at least, the Marriott, Hilton and Starwood chains) commonly will quote a price per night in dollars or euros, but will charge in local currency. One supposes that when/if the nation converts to the euro (as Poland, Hungary and a few others are planning to do) the problem will go away as to them, but for the time being the "quote in Euro, charge in Zloty" practice results in the charge per day bouncing around.

I have a hotel bill from a recent three-day trip to Warsaw where the room rate was quoted in Euro (€151 per night to be exact) but was charged by converting the Euro amount into Zloty (PLN) at the daily rate. This meant that my bill showed PLN 648.41, 647.24, and 645.44 respectively for the three nights.

As you can see from the progression, the Zloty was firming against the Euro during my stay, so the amount I was charged (on the day I checked out) resulted in the room actually costing €151.70 the first night, €151.42 the second night, and €151.00 the third night. Compared to the credit card conversion costs, that variance is budget dust, but it's sort of interesting to see a hotel bill with different rates for each night.

That's what I wondered, too. Maybe I'll ask at check-out next time it happens.

I agree.
