For bookings made on the World Hotels Stay in Europe, pay in dollars promotion, guests from North and South America can pay for the quoted Euro rate in US Dollars, a saving of around 40%. The promotion runs until 31 August 208, for stay from Thursdays to Mondays at participating hotels. I did have a look at the list of participating hotels and there did seem to be a reasonable number.

You need to telephone 800-223-5652 or book through a travel agent, the offer is not available online.
