Hi! We spent 6 months in Prague, and, while I do not have any point-earning/membership hotels to suggest, I highly recommend Hotel Savic. (http://www.tripadvisor.com/Hotel_Rev...e_Bohemia.html). Our guests found it to be really charming and quaint as well as well-located. If you need any recommendations or other help feel free to PM! You'll have a great trip! :-)
