If you're young, hip and want to party all night long, then head for the Shore Club on perennially trendy South Beach. Jessica Simpson and her sis Ashlee have both been spotted here, as have John Mayer and Matthew McConaughey. Equal parts sleek-and-chic Miami Beach and light-and-airy Matisse, this exclusive hotel features plenty of discreet garden corners for hiding away. Although the standard rooms are nothing to sneeze at, you're not likely to find the A-listers checking into one. Instead, they opt for the designer bungalows or 6,000-square-foot triplex Penthouse. But even the rich and famous have to come out and play sometime, so book a table at Nobu or find yourself a prime viewing perch at the sexy Skybar. And if you need a break from the rigors of celeb hunting, slip away for a treatment at the divine spa.
