Has everyone checked the conversion rate that they are getting from their credit cards? I used my Chase Sapphire Visa (double points on travel) and was charged $977 (US dollars) for a reservation that is 592 British pounds. This is more than $100 more than I expected from the on-line conversion rates. It's still a good deal compared to the U.S. sites, just not quite as good a deal as i was expecting.
Any other conversion-rate experiences?
I cancelled my original 3 nights at CBR in March and rebooked with the 10% promo code. My total was 229.59 GBP, which converted to 377.90 USD on the conversion site I used. My credit card (Capital One *********** - 1.5% cash back on all purchases) was charged 378.81 USD, so it was very close to what I was expecting.
Are you sure you were converting British pounds sterling? When I plug your 592 GBP into the website I used, www.coinmill.com, I was given 974.43 USD.
