Karlovy Vary Czech Republic 36001
The Imperial dates back to the early 20th century and has hosted Russian royal families and Hollywood stars, including Mary Pickford and Douglas Fairbanks. But the services at this hilltop compound remain up to date. Guests spend their days taking in pleasant views and sipping the region's famously restorative mineral water (but don't ask for free refills). A premium spa package includes free lift tickets on the cable car into town and enough treatments to soothe embattled world leaders.
