I have a helluva time with South American stays. It's hit or miss whether they post, and when they do, the are always WAY off.
For example I recently stayed at the Marriott Santiago. They gave me 1621 points for a 5 night stay...thats $162. Trust me, I didnt have THAT good of a rate! Of course a fax of the bill fixes things up, but it's a hassle to always chase your points. It seems to me that they have some issues with the currency conversion algorithym.
