Traveling in style: 4 over-the-top hotel rooms only millionaires can afford

Forget scratchy comforters and crowded buffets. When the super rich go on vacation, they do it in style, staying at the best hotels money can buy.

CNBC's "Secret Lives of the Super Rich" highlights several of these over-the-top rooms, where on-call butlers, private elevators and in-suite theaters are the norm.

Here are a few highlights of the lavish hotel suites featured on the show's fourth and fifth seasons, including everything from gold-covered ceilings to invite-only rooms.

The Nobu Hotel in Caesar's Palace Las Vegas is home to a secret $35,000-a-night penthouse, complete with a rooftop hot tub, which originally had to be delivered via helicopter. The room has been booked by a number of celebrity clientele, including Justin Bieber, Miley Cyrus and Taylor Swift. The suite covers 10,000 square feet and features a host of amenities, including a private sushi chef.

At the St. Regis Abu Dhabi, one suite is suspended between the hotel's two towers, appearing to "float" nearly 700 feet above ground. This suspended room is the highest of its kind in the world. The 12,000-square-foot suite has its own private elevator and runs $47,000 per night. The suite is decked out with gold ceilings, floor-to-ceiling windows, 19 chandeliers and marble counter tops, worth more than half a million dollars. It's also packed with amenities ranging from a private theater to a sauna to an on-call butler.

The Venetian hotel in Las Vegas reserves a handful of its more than 3,000 rooms for V.I.P. clients, available by invite only. The rooms themselves are free, but patrons more than pay for their stays at the blackjack table: The more you're willing to spend in the casino, the better the room you're given. The lucky high rollers who are invited to The Venetian can take advantage of in-room theaters, private bars and 24-hour butler service.

If living in a hotel doesn't already sound like a dream, the 39th floor of New York City's Pierre hotel can be rented out for a whopping $500,000 per month and comes with a fleet of staff. They do everything from delivering room service to lighting candles to drawing elaborate baths for guests. The 4,700-square-foot space also includes a private chauffeur and incomparable views of Central Park.
