Can anyone tell me what hotel(s) are used in Madrid for the 8 days in Barcelona and Madrid tour?
The hotels vary from tour to tour. You can call the RS office and get a definitive answer if you are signed up for one of the tours. Or you can search the RS scrapbook archives to find names of hotels used on previous tours.
