The Penthouse Suite (The Martinez Hotel, Cannes)
This is the priciest hotel room in the French Riviera. The place itself is already a favorite destination for the rich and famous and therefore, naturally expensive. If you happen to be one of these rich and famous, staying in this suite will set you back $18,000 a night. You get your own wrap-around terrace (with gorgeous views of the Lerins Islands and the Bay of Cannes, of course), kitchen, open bar, and a private butler. A note on the 2,000 square feet terrace: it can hold up to 100 people.
