When booking on the website you are only getting an illustration of the currency conversion, not booking the room under a different currency.

This is posted under the currency box on the website:

The currency conversion is for comparison only; your reservations will be booked in the local hotel currency displayed. Currency rates utilized in each conversion rely upon several different public sources from other parties without independent investigation or verification and should be used only as examples. Hilton does not, and cannot, verify the accuracy of any rate conversion examples.


i.e.: When I change the currency on a hotel in the US to Swedish Krona it will give me a quote in Krona, but when I proceed to book the room it will display the price in USD as that is the local currency on the reservation. This thread may be of help if you are trying to avoid DCC.
