Bed down at one of Nick Lachey’s or Eva Longoria’s favorite haunts. Rise and shine atop the trees in an open-air suite with authentic Bali bridal bed. Soak in sybaritic abandon in a “levitating” tub or sip your martini (shaken, of course, not stirred) in a suite recalling the world’s most debonair spy. And if you have to ask the price for these outrageously decadent retreats, best pack your bags for more mundane parts – because while sleeping ‘neath the stars is possible, sleeping like the stars can be extremely hazardous to your bank account.

Haute hotel-within-a-hotel

Hotel Beaux Arts Bathroom smForget hidden passageway – here’s an entire trio of luxurious floors with 30 rooms and 14 suites tucked away in another hotel. Ultra-modern, urbane and exclusive, the Hotel Beaux Arts Miami is sheltered within the JW Marriott Marquis on floors 39, 40 and 41.

Here, the likes of Eva Longoria and Sheila E are whisked from the spotlight to refresh and retreat in sleek surroundings with views overlooking the city from floor-to-ceiling windows. Within, views are equally impressive, with teched-up rooms warmed with Brazilian cherry wood floors, Italian marble bathrooms with touch-controlled faucets and one-of-a-kind pieces of artwork.

Guests also enjoy access to the JW Marriott Marquis’ entertainment complex, comprising Jim McLean Golf School, NBA-approved basketball court and virtual bowling alley, as well as a 3D Media Room on the 19th floor and a 2nd floor chocolate shop, wine boutique and vue lounge overlooking the Miami River. Rates begin at $449/night.

Decadence, sheer decadence

James Bond SuiteTucked into the Latin Quarter near the famed Jardin du Luxembourg, the Seven Hotel, a luxury 35-room boutique Parisian hotel and member of Sterling Design, is renowned for impeccable service, “glowing” rooms and . . . levitating tubs and beds. Cloud-comfy beds and soaking tubs appear to hover inches above the floor; both usher guests blissfully into nirvana. Rates start at $306/night.

Even more over-the-top is the hotel’s 007 Suite. This bach pad a la “The Spy Who Loved Me” is as suave as you might expect, with mid-century modern detailing and a silhouette of a Bond girl in all her come-hither glory. Step into the Turkish bath steam shower or avail yourself of the entire James Bond movie library. It’s easy to deduce why it’s a Preferred Hotel Group hotel. Rates begin at $576/night.

From sterling silver to leafy green

One suite shines with hand-hammered sterling silver furniture; another sports a safari vibe tempered by a Caribbean sensibility. Both are extravagant retreats set amidst Curaçao’s breathtaking scenery of cliffs falling away into the sea.

At Hotel Kura Hulanda Spa & Casino, an 80-room luxury boutique resort and member of Leading Small Hotels of the World, the Indian Bridal Suite is a paean to precious metal. Its centerpiece: a sterling silver four-poster king size bed whose corners are coquettishly draped and tasseled. Steps away is an Indian marble soaking tub with tiered entry.

The suite is situated over the resort’s Indian Marble Garden, lush courtyards and two swimming pools, and located in a village setting comprising the Museum Kurá Hulanda – an internationally renowned anthropological museum – a European split-level boutique casino and the Spa Kura Hulanda.

At sister property Lodge Kura Hulanda, the Tree House Suite channels guests’ inner Swiss Family Robinson for adventure atop verdant island foliage. Follow the spiral staircase up and into the open-air living room with its ornate Bali Bridal bed. The sun melts into water’s horizon right outside the windows, returning in the morning to warm the Caribbean sea for a day of snorkeling and sand castle building.

The roomy two-bedroom, two-bath suite is laden with antiques, and civilizes the Robinson experience with 300-thread Egyptian cotton sheets and comforters, flat screen TV and wireless Internet. For either suite, rates begin at $1,000/night; when you book three nights you get a fourth night free.

Commune in nature

Jade MountainSettle into the same decadently lavish sanctuary at St. Lucia’s Jade Mountain that Nick Lachey recently shared with his wife. Traverse the private bridge to your room – or sanctuary – and submit to the charms of this Caribbean refuge that is completely private yet fully exposed to the naturescape. With the fourth wall absent, guests may embrace Nature in all her glory – not to mention million dollar views and private infinity pool that seems to shimmer right into the sea.

Each of the 24 individually designed sanctuaries feels like its own parcel of paradise with plenty of space for lounging and lazing. A round-the-clock butler service, trained a la the British Guild of Butlers, provides guests your-wish-their-command service. Topping it off: (optional) in-room spa therapies – the three-therapist Ménage-A-Spa is a specialty – and a soft sandy beach mere steps away. Rates start at $1,275/night for the winter season.

King of rock ‘n roll room

Graceland HRCBook the Graceland Suite at the Hard Rock Hotel Orlando, located in Universal Orlando Resort, and feel pampered and indulged with 2,000 square feet of over-the-top amenities. A baby grand piano, 65” flat panel TV, whirlpool tub, glass-encased double-sided fireplace and more greet guests in a color scheme that Elvis himself would croon about.

The suite feels rock star-right in this hotel with celebrity mansion design sporting sweeping California mission-style facades and lavishly expansive palm-lined swimming pool. Trimmed with white sand beach and cabanas, the pool pumps up the volume with underwater music. Guests may avail themselves of the comestibles at the legendary Palm Restaurant and VIP access to Universal Studios and Islands of Adventure theme parks. Graceland Suite occupants also gain exclusive admittance to Club 7 Lounge. Rates begin at $1,875/night.

A room with a view

The world is your oyster – or your Big Apple – with a stay in the Presidential Suite inside the Mandarin Oriental in NYC. Rising 53 stories into the New York skyline, this urbane enclave with custom-designed furnishings calms and cossets travelers with panoramic views – from the living and dining areas and the large soaking tub and glass-enclosed steam shower for two – and a color palette of chocolate-brown accented with luminous brushed gold.

A restful hush permeates this suite’s 2,640 square feet by way of upholstered silk walls in the bedroom, Mozambique wood paneling in the study, well-swaddled goose down bed and handcrafted oriental rugs throughout. A Nespresso coffee machine beckons from the gourmet kitchen and Bang & Olufsen televisions promise superior quality. The price tag? Rates start at $18,000/night – but includes a concierge team that can handle any request with aplomb, including renting a movie theater for private screenings.
