The biggest hotel in the world by number of rooms is First World Hotel at Resorts World Genting in Malaysia. It has an enormous 7,351 operational rooms spread across three towers, too many to be compared to many normal hotels. First World Hotel is the largest hotel in terms of rooms, as recognized by Guinness World Records, and Resorts World Genting still considers it the world’s largest hotel in 2026.

The hotel is part of a bigger entertainment resort, where you can enjoy shopping, restaurants, attractions and convention facilities located in Genting Highlands. It’s not a matter of constructing the grandest hotel in the world. It’s all about hosting a large number of guests in an effective way.

Why Do The Biggest Hotels Get So Big?

A one or two storey hotel is what most hotels require. It is only a property that is so big when it’s always getting a huge amount of visitors.

Mega-hotels can attain this size for a couple of reasons.

• The demand of tourists – The large entertainment centers can receive thousands of visitors a day.
• Casinos and attractions – Large Resorts: Many big resorts offer hotels, casinos, shopping and entertainment in the same complex.
• Convention business – Hundreds or thousands of rooms are needed simultaneously for large meetings and events.
• Affordable rooms – There are many relatively small rooms in a hotel which makes it much more affordable.
• Several towers – Mega-hotels can be expanded by multiple towers that are connected together rather than having all of their rooms in one building.

Almost all of these are present in the first world hotel. It is located in Resorts World Genting, surrounded by attractions like First World Plaza, SkyAvenue, Skytropolis Indoor Theme Park and Genting International Convention Centre.

The Biggest Hotel That Holds the Record

First World Hotel was originally renowned for its large number of rooms but grew larger as the hotel expanded. According to Guinness World Records, the hotel went from 6,118 rooms to 7,351 rooms after the construction of the Tower 2 Annex. The reading was taken on 20 June 2015.

The hotel is now divided into three towers and has multiple types of rooms. The standard rooms, the deluxe rooms and the triple and the world club rooms are available, and the newer Y5 rooms are in Tower 3. Many common rooms are about 180 square feet, and are focused on being utilitarian, not cluttered with lots of private space.

This is a significant aspect of what made the property so considerable. The majority of First World Hotel spaces are fairly small rather than large suites.

7,351 rooms at a single hotel complex could be a half full on a specific night, but still be thousands of guests sleeping in the same building.

The Biggest Hotel Doesn’t Mean Tallest Hotel

That’s where things get a bit confusing with the record.

First World Hotel is the biggest hotel based on the number of rooms, but it is nowhere near the world’s tallest hotel.

The record is held by Ciel Dubai Marina, Dubai. It was officially recognized as the tallest hotel, with 82 floors and 1,004 hotel rooms by Guinness World Records at a height of 377.127 meters. This record was set on December 9, 2025.

Thus, the two records are measuring completely different things.

First World Hotel’s victory is due to capacity. Ciel Dubai Marina is a winner due to its tallness.

An excellent illustration of the need for the expression “biggest hotel” to be explained. Biggest can mean number of rooms, floor area, height or size of a resort complex. However, when it comes to hotels based on the number of guest rooms, First World Hotel is at the top. 

Other Massive Hotels Worth Knowing

First World Hotel is not the only hotel built on an extraordinary scale. Several properties around the world contain thousands of rooms.

The Venetian Resort in Las Vegas is another giant. The combined resort includes The Venetian and Palazzo towers and has thousands of suites, putting the complex close to First World Hotel in overall accommodation capacity.

Abraj Al Bait in Mecca is massive in a different way. The overall complex was designed to accommodate about 65,000 people, according to Guinness World Records. Its central Hotel Tower rises 601 meters and forms part of one of the world’s largest building complexes.

MGM Grand Las Vegas is another famous example. It opened in 1993 with more than 5,000 rooms and was once considered the world’s largest hotel by room count. Renovations have changed its room total over the years, but it remains one of the largest single hotel buildings in the United States.

Then there is Abraj Kudai in Mecca. The planned project attracted worldwide attention because designs called for roughly 10,000 hotel rooms across 12 towers. If completed according to those plans, it could exceed First World Hotel’s room count. However, the project has faced major delays and has not replaced First World Hotel as the operational record holder.

What Is It Like Inside the World’s Biggest Hotel?

Despite its world record, First World Hotel is not built around extreme luxury.

Many of its rooms are compact and practical. Standard and Deluxe rooms are roughly 180 square feet, while larger World Club rooms offer around 430 square feet of space. Different towers offer different room types depending on budget and group size.

The real advantage is location.

Guests can move from their hotel to shopping, indoor entertainment, dining and convention facilities without traveling far. Resorts World Genting itself has more than 10,000 rooms and suites across seven hotel properties, making the broader destination considerably larger than First World Hotel alone.

That setup explains the property’s enormous size better than the room number alone. First World Hotel functions almost like accommodation infrastructure for an entire entertainment destination.

Could an Even Bigger Hotel Take the Record?

Absolutely.

Hotels are constantly being proposed in rapidly developing tourism markets, and several projects have announced room counts large enough to challenge First World Hotel.

The most famous example is Abraj Kudai. Plans for the Saudi Arabian development called for approximately 10,000 rooms, 12 towers and dozens of restaurants. On paper, that would comfortably beat First World Hotel.

But proposed size and operating size are two different things.

Hotels can experience construction delays, financing problems or major design changes. Until another completed and operational hotel exceeds 7,351 rooms and has its record verified, First World Hotel remains the benchmark.

This is similar to other architecture records. A bigger project on a drawing board does not automatically replace the building that currently holds the title.

Why Build 7,351 Rooms in One Hotel?

The answer has a lot to do with Genting Highlands itself.

First World Hotel is not standing by itself in an ordinary city neighborhood. It sits inside Resorts World Genting, one of Malaysia’s major leisure destinations. Visitors arrive for entertainment, theme parks, shopping, dining, conventions and other attractions.

That creates an unusual demand problem.

Instead of accommodating only a few hundred visitors, the resort may need space for thousands. Building thousands of rooms close to the attractions allows more guests to stay directly at the destination rather than traveling back and forth.

The hotel therefore works less like a traditional luxury property and more like an enormous accommodation system.

That may not sound as glamorous as a hotel with gold-covered suites and private elevators, but from an engineering and hospitality point of view, handling thousands of rooms is impressive in its own way.

Final Thought

First World Hotel is the biggest hotel in the world in 2026 when measured by number of rooms, with 7,351 rooms at Resorts World Genting in Malaysia. Guinness World Records continues to recognize it as the largest hotel by room count.

It should not be confused with the world’s tallest hotel. That title belongs to Ciel Dubai Marina at 377.127 meters. Other enormous properties in Las Vegas, Mecca and elsewhere also compete on scale, but none has yet taken First World Hotel’s room-count record.

What makes the hotel interesting isn’t simply that it has thousands of doors. It is the reason those rooms exist. First World Hotel was built to handle the huge flow of people visiting an entire entertainment destination. And with 7,351 rooms under one hotel name, it remains a scale of hospitality that few properties in the world come close to matching.
