I have a card with country set to the US that it is not letting me remove because I used it for another stay and I think because of that it is setting the currency of any other card I add to the US too even if I use a different billing country.

I even tried Paypal which showed local currency initially but even with that they try to charge me in USD because that is where my Paypal account is located.

This is nothing but a 3% money grab and they're clearly being obstructionist about letting you use the local currency (in fact, the functionality used to exist according to posts on the Internet until the bas*ards blocked it). I intend to initiate a chargeback after my stay on the grounds that they are doing dynamic currency conversion without offering me the opportunity to pay in local currency, which I believe is against the rules of Visa and Mastercard. I'm not a lawyer, but I hope a class action is filed about this.
