Hey, high rollers, big spenders, and “Winner, winner, chicken dinner!” shouters: We’ve got some suites for you. When it comes to Las Vegas, a suite is more than just a suite: It’s a villa, a penthouse, a bungalow — sometimes (ahem, Bellagio) it’s an estate.

We’re not kidding! For the best of the best, you can enjoy in-room elevators, 24-hour butler service, glass-enclosed lap pools and Jacuzzi hot tubs, movie theaters, full spa and salon services, fireplaces, rain showers, terraces with plunge pools, and courtyard gardens without ever leaving your “room.” So,  cash in your chips and get ready to cash out with one of these 15 über-luxurious dream pads. It’s no gamble: You’re sure to feel like you’ve died and gone to Sin City once you do.

1. Two Story Sky Villa, the Palms Casino Resort 

Previously named the Hugh Hefner Villa, the 9,000-square-foot Two Story Sky Villa at the top of the Palms Casino Resort is certainly a mansion fit for a king. With a private glass elevator, 24-hour butler service, and your very own indoor infinity pool that hangs off the edge of the penthouse and overlooks the Strip, you may as well rock Hef’s signature slipper shoes because there’s no reason to leave the Sky Villa. Did we mention the massage, sauna, and fitness rooms? Oh, and the round, rotating bed situated beneath a matching ceiling mirror.

2. Penthouse Suite, The Venetian Resort

After taking a romantic gondola ride through the Venetian’s Grand Canal and admiring the color-changing sky ceiling, continue to be transported to Venice by staying in your very own Italian palace. Occupying the highest three floors, this regal 2,900-square-foot Penthouse Suite is the ruler of all the suites in Venetian land. Open the double doors, walk through an Italian marble foyer, and claim your throne inside the massive open living room as you peer out beyond the Roman shades flanking the windows. Continue to imagine that you are in a land far away (and one that isn’t 100 degrees) when you cap off the night by the master bedroom’s fireplace.

3. Wynn Fairway Villa, Wynn Las Vegas

Nothing says indulgence like this one-of-a-kind suite at the Wynn Las Vegas. The silk and ivory upholstered interiors and panoramic golf-course view from inside the property's 3,000-square-foot, two-bedroom Fairway Villas do not disappoint. Pour yourself a drink from the mahogany and marble wet bar, hop on the private massage table, wash off in a rain shower, and then soak in the sights from your private pool and terrace.

4. The Sake Suite at Nobu Hotel, Caesars Palace 

Inside Caesars Palace sits a hotel within a hotel: the world’s first Nobu Hotel, comprising 181 rooms and suites. Opened by chef Nobu Matsuhisa and his partners, including Robert De Niro, in early 2013, this exclusive experience offers more than just yummy Nobu room service. The 1,300-square-foot, one-bedroom or 1,950-square-foot, two-bedroom Sake Suites welcome you with Nobu’s signature hot tea and entice you with a custom Japanese expressionist bar and lounge area. Outside the suite, head to the ground floor for priority seating in one of the first-ever teppanyaki rooms and group pod lounges at the world’s largest Nobu restaurant and lounge, trek across Caesars for complimentary access to Pure Nightclub, and enjoy complimentary access to a private Nobu concierge.

5. Sky Villas, ARIA Resort and Casino

Travel up the spiral wood-and-metal staircase to truly soak up the floor-to-ceiling view from inside the property's modern, tech-savvy, and convenient (hello, in-room elevator bank!) Sky Villas. Ranging from 2,000 to 7,000 square feet, two or three bedrooms, and one or two stories, your lap of luxury could include a 12-person formal dining room, an exercise room, or a private salon. All of the suites offer 24-hour butler service, billiard, massage, and steam rooms, a complimentary limo ride to and from the airport, and a private check-in lounge, which isn’t a too-shabby start. And if you feel blissfully paralyzed after that rainforest-misting shower upstairs, have no fear: Everything in the suite is remote-controlled.

6. The Bungalows, The Cosmopolitan of Las Vegas

The Cosmopolitan knows that you’ve come to Vegas ready to party, and it also knows that you like the VIP treatment -- which is why its Bungalow suite is so amazing. With direct pool access from the first floor, you can experience the hotel’s raging all-day DJ pool party without ever waiting in line. There’s no need to order a day bed with bottle service, because your butler will take care of the mixed drinks. And if you want to make friends with fun-loving pool partiers, just invite them inside. Downstairs, the media room, bar, and couches can serve as your own personal hangout space. And, on the terrace (above the bedroom suite, which has full-length mirrors that reveal themselves as TVs), a Jacuzzi plunge pool awaits.

7. Skylofts, MGM Grand

VIP treatment is one thing when it comes to partying, and it’s another entirely when it comes to living. The Skyloft experience at MGM rolls out the red carpet in every way. There’s an “intimate” 1,400-square-foot one-bedroom; a 3,000-square-foot, two-bedroom loft with a wet bar, pool or foosball table, and multiple living areas; a 4,800-square-foot two-bedroom with an outdoor patio, plunge pool, and private workout room; or a massive 6,000-square-foot three-bedroom with — you guessed it — the works. Plus, you get your own personal butler and concierge. When you get a complimentary pickup from the airport in a Rolls-Royce, why would you expect anything less?

8. The Villas, Bellagio Hotel and Casino.

Whoever says that you can’t relax in Vegas has never stayed at The Bellagio. The Villas up the ante when it comes to enjoying the finer things in life. The European-designed 6,500-square-foot, two-bedroom and 8,000-square-foot, three-bedroom estates (they actually deserve to be called estates) come with every amenity imaginable. After your limo drops you at the private entrance, head to your room where welcome fruit and candy and your favorite beverages await. Wander from the private workout room to the massage room and dry sauna, through the hair salon, his-and-her bathrooms, and into the formal dining room and bar — and don’t forget to say hi to your butler! — before stumbling upon a little piece of paradise: a quiet courtyard garden with chaise lounges, a pool, and a fireplace.

9. Presidential Strip View Suite, Four Seasons Hotel Las Vegas 

With wraparound floor-to-ceiling windows from the top five floors of the Mandalay Bay main tower, the Four Seasons Hotel Las Vegas shows its hand with the Presidential Strip-View Suite. The 2,225-square-foot modern sanctuary (there is one on each floor) boasts a dining room for eight, oversize living room, full kitchen, and media and data hubs. Even in Las Vegas, you get the tranquil Four Seasons experience, with a private lobby, health and spa, pool, library, and even restaurants Charlie Palmer Steak and Verandah. If it starts to get too quiet, join the chaos downstairs at the Mandalay and marvel at the famous Shark Reef Aquarium.
