The Setai Miami Beach Rating: 5.0 Pearls
Seductively dark, Asian-inspired design; impeccable service; huge, immaculate rooms; three pools (each a different temperature); and a prime beachside location make the exclusive Setai one of the best -- and most romantic -- hotels in South Beach. The sleek yet opulent rooms come with a black granite soaking tub right by the foot of the bed. In the bathroom, there's a sexy, freestanding rainfall shower with floor-to-ceiling black tiles.
The Resort at Fisher Island Club Rating: 5.0 Pearls
Located on a lush, Mediterranean-style private island, Fisher Island feels dramatically disconnected from the Miami masses. The hotel's 45, mostly freestanding guest rooms and villas center around a historic mansion built by William Vanderbilt II, now home to an elegant lounge with a nightly piano player and tuxedoed waiters. In a center courtyard, peacocks roam freely underneath a massive ficus tree. Opt for one of the seven "Courtyard Gardenview Villas" -- they have their own private yards with Jacuzzis and gorgeous, just-renovated bathrooms with freestanding tubs.
The Ritz-Carlton Bal Harbour, Miami Rating: 4.5 Pearls
Opened in 2008, the Regent -- one of Miami's leading luxury hotels -- boasts the impressive, 10,000-square-foot Guerlain spa, with treatment rooms overlooking the ocean. But the rooms are the real draw -- specifically the bathroom, which comes with a freestanding bathtub that sits beneath broad floor-to-ceiling windows and is big enough for two. Plus, you can always score points with your partner by arranging a shopping extravaganza at the exclusive Bal Harbour Shops, five minutes away.
The Tides South Beach Rating: 4.5 Pearls
Bright, massive, elaborately designed rooms -- all overlooking the ocean -- and private designated assistants to attend to your every whim make the Tides a popular choice among South Beach honeymooners. Marble-lined bathrooms feature deep soaking tubs, and the intimate pool, restaurant, and coral bar all come with especially attentive yet discreet service.
W South Beach Rating: 5.0 Pearls
With one of the sexiest pools in Miami, surrounded by dense palms, colorful cushions set along the grass, and wood-lattice cabanas, W South Beach is a great spot for couples looking for a romantic -- and relaxing -- getaway. As a W hotel, it features the top-notch Bliss spa (which offers couples massages, among many other treatments), and large, modern rooms with uber-sexy bathrooms complete with luxurious showers, double sink vanities, and Bliss toiletries.
