Opulent: These are the World's Most Luxurious Hotels

When it comes to the most expensive, elegant, and stylish hotels in the world, only one rule applies: More is more! These hotels juggle with stars, involve multi-billion-dollar constructions, and splash out on gold and marble decor.

A room in one of these exclusive domiciles might be unaffordable for most travelers, but dreaming and marveling are always allowed. Let's get started: We'll show you some of the most luxurious hotels in the world!

There is no hotel in the world more talked about than the Burj Al Arab in Dubai. This luxurious hotel set out to break all records from the very beginning and markets itself as a seven-star hotel, although the official rating ends at five stars.

The architecture alone is spectacular: The Burj Al Arab stands like a sail amidst the Dubai skyline. It features nine restaurants and bars, a gigantic spa, and all things exclusive: a rooftop helipad, private butler service, and check-in on iPads plated with gold.

An overnight stay in the cheapest suite-there are no regular rooms, only suites-costs around 1100 Euros, with the most expensive accommodation being the Royal Suite, which has hosted Justin Bieber. Price: from 11,000 Euros.

What Dubai can do, Abu Dhabi can do for a long time-or at least that's what one might think when comparing the two emirates and their luxury hotels. A rivalry? Quite possible. The Emirates Palace in Abu Dhabi is definitely luxurious.

It boasts a private beach and marina and offers services for the wealthy-from a personal butler to a private helicopter or jet. With a bit of luck, you can snag a room starting at around 250 Euros in the off-season. Typically, room prices start from 500 Euros, with suites beginning at 1000 Euros.

The concept of a seven-star hotel is also significant in Italy. In Milan, the Townhouse Galleria in the chic shopping arcade Galleria Vittorio Emanuele II has been a luxurious fixture since 2007-and was even renamed 'Seven Stars Galleria'. The upscale hotel is situated directly above Prada.

The hotel obtained a seven-star certificate upon opening, which has not been renewed, but the luxury remains unbroken. The hotel has 25 suites, each uniquely furnished. Every guest, regardless of gender, has a butler at their service. Bookings start at about 1250 Euros per night, and breakfast costs an additional 30 Euros per person.

In Venice, there is also a hotel that plays up the seven-star hype: The Aman Canal Grand is a decadent residence. Guests who check into the opulent 16th-century palazzo experience breathtaking views of the Grand Canal, amid gilded doors, historical frescoes, and lavish chandeliers.

Quirky side note: When George Clooney married Amal Alamuddin in 2014, they booked all 24 rooms in this hotel and 95 more rooms in another luxury hotel. Alleged cost: $3 million. Rooms are priced just under 1000 Euros in the off-season but can rise to 4000 Euros.

In any TV series set in New York City, if a hotel is mentioned, it is almost always the Plaza. This luxurious establishment is renowned far beyond the Big Apple's borders and has long been an institution on 5th Avenue.

A stay here provides not just a place to sleep but also a substantial dose of lifestyle. Numerous luxury shops, an upscale spa, multiple restaurants, bars, and cafes-and even its own food hall-are on offer. An overnight stay in a basic room starts at about 500 Euros, while the most expensive suite starts from 25,000 Euros per night.

Bigger, taller, more colorful, more expensive: When it comes to the most luxurious hotels in the world, the glittering spot in the USA cannot be missing. In the casino metropolis of Las Vegas, countless opportunities abound for opulent stays on the Strip. The most famous is the Bellagio, known from many TV series.

Interestingly, the hotel complex is designed to resemble the landscape of Lake Como. It features a 3.2-hectare artificial lake, a luxury shopping arcade, a casino, and two wedding chapels. With some luck, you can snag a room starting at around 250 Euros in the off-season, though regular prices are higher, beginning at 600 Euros. A resort fee of $45 applies per room.

Much like the Plaza in New York, the Ritz in London is a legend: Everywhere you look, it sparkles and glistens. The Tea Room Palm Court, styled after Louis XVI, is famous, with guests including Queen Elizabeth, Winston Churchill, and Charlie Chaplin, who enjoyed their afternoon tea there.

The hotel's former ballroom houses the Ritz Club Casino, known as one of Europe's most exclusive privately run casinos. Off-season, rooms start at around 900 Euros, with regular room prices beginning at approximately 1700 Euros. The most expensive is the Deluxe Suite, starting at 5900 Euros per night.

On the other side of the world, Singapore entices with numerous luxury hotels. One stands out not just for its high level of luxury but also for its rich history: the legendary Raffles. It has survived multiple wars, the Great Depression of the 1930s, and various changes in hotel ownership unscathed.

In 1991, it was renovated, boasting even more luxury and charm. Fun fact: It even has its own resident historian! A room can be secured starting at about 800 Euros, but standard prices range higher-from approximately 1000 Euros to 3000 Euros.

During the legendary Cannes Film Festival, the Hotel Martinez becomes the main attraction. Opened in the 1920s, this sophisticated hotel has become a meeting point for celebrities. Each year during the festival, it hosts stars from the red carpet.

The hotel offers three elegant restaurants, with notable guests such as Clint Eastwood, Jennifer Aniston, or Quentin Tarantino. To stay here, you need at least 400 Euros for a room. A night in the prestigious Prestige Suite starts from about 2000 Euros.

Antalya might be known for package holidays, but it has more to offer in the popular vacation destination. The Mardan Palace is considered one of Turkey's most extravagant hotels. With a construction investment of 1.6 billion US dollars, the cost to stay reflects that. During the off-season's colder months, rooms start at around 220 Euros, but in the summer, room rates climb to approximately 900 Euros.

Allegedly, 10,000 square meters of gold leaf, 500,000 crystals, and 23,000 square meters of Italian marble were used in the construction. Amenities include the largest pool in the Mediterranean, a vast spa, and a private artificial beach made from Egyptian sand.

In the French-speaking region of Switzerland, in Geneva, lies one of the world's most distinguished hotels-by Lake Geneva and close to the Swiss Alps. Celebrities like Michael Jackson, Bill Gates, and Bill Clinton have already visited here.

Fun fact: The Royal Penthouse Suite features a sumptuous Steinway & Sons grand piano, ensuring that pianists feel right at home. Room rates start at about 600 Euros. If staying in the Royal Penthouse Suite, the price escalates to a princely sum: 49,000 Euros per night.

In Berlin, the Hotel Adlon is considered a legend, now operated under the name 'Adlon Kempinski'. It was opened in 1997 and follows the tradition of the 1907 hotel, which burned down in 1945, except for a side wing that stood until 1984.

Today, celebrities like Angelina Jolie, Brad Pitt, or Harrison Ford check into the hotel's luxurious suites. Room rates start at around 400 Euros per night. However, it's a different story for the Royal Suite: It costs over 18,000 Euros per night. Fun fact: The restaurant serves currywurst garnished with gold leaf powder.

In the City of Love, hotels are all about luxury as well. One of Paris's most exclusive hotels is the Plaza Athénée on Avenue Montaigne. It offers a unique view of the city's major landmarks, and inside, it's sheer luxury.

The hotel features five restaurants overseen by Michelin-starred chef Alain Ducasse, a luxurious spa by the Dior Institute, and more than 80 drinks in the minibar. It comes at a price: Rooms start at about 1800 Euros in the off-season. A night in the Haute Couture Eiffel Suite is quite the investment: starting at 20,000 Euros.
