Mandarin Oriental Hotel

From the Mandarin Hotel Group. This is considered the most luxurious(and expensive)of them all. The facilities are top notch and so are the staff (depending on when you go, their turnover is way higher than it should be for a luxury chain of this size and reputation). It is commonplace to find rappers and A-listers in the pool or walking through the lobby. It is also isolated on it's own island (Brickell Key) which to some seems more of a hassle than an amenity.
