Race Info
Karlovy Vary is the site of numerous hot springs and is the most visited spa town in the Czech Republic. The city has been used as the location for a number of film-shoots, including the 2006 films Last Holiday and box-office hit Casino Royale, both of which used the city's Grandhotel Pupp in different guises. Moreover, the Palace Bristol Hotel in Karlovy Vary had been used as a model for The Grand Budapest Hotel movie. Source
