That's the curious thing about how some HIs are priced. I am using a 15K award in Warsaw in two weeks. This is one of the best properties in the city, and the room rate is US$200+ on the web site. As noted, the same 15K will get you a mediocre HI stateside, worth US$75 a night. In the US, major city HIs like NYC go for 25K a night, though you can get a room for slightly over US$125 on the site.
ICs, which generally go for US$300+ per night in most cities, run 30K.
So you figure.
