And taking some fresh $100 US bills with me also. kennycrudup info was helpful as well. Will try to remember to post data points late next week after arrival.
As another poster above pointed out, if you pay cash for your hotel, you're subject to the 20% tax. So, even if the Visa/MC rate is a bit less than the full cash/Western Union exchange rate, you're probably still well ahead using the credit card. And, you don't have to carry a bag of cash, which is what I literally saw last year at the Hyatt. It was kind of comical, but also a bit cumbersome to walk around with that much cash.
If you need an exchange place, your hotel can usually refer you to someplace nearby that is reputable.
