I am new to the forum, so please feel free to rag on me if this has been discussed. I couldn't find the search function. In Hotwire, when you click the "Amenities" link, you get sent to a URL, with an identifier number in it. That last set of numbers must be an identifier for the hotel. I don't know if it changes or anything. If it doesn't, that number could be a better way to identify the hotel. If you can't see the number, it displays in IE7, I don't know about other browsers. Anyways, maybe this'll be a better way to identify the hotels.
