September 20, 2026: Hotels are often associated with luxury, comfort and personalized service, but some properties around the world operate on a completely different scale. With thousands of rooms, extensive entertainment facilities, restaurants, shopping areas and convention spaces, the world’s biggest hotels can resemble small cities rather than traditional accommodation businesses.

Based on publicly available figures, First World Hotel in Malaysia currently stands at the top of the list by reported room count, followed closely by The Venetian Resort in the United States. The ranking also highlights the extraordinary concentration of mega-hotels in Las Vegas, while major hospitality complexes in Saudi Arabia, Macau, Russia, Thailand and Japan also feature prominently.

Because room inventories and reporting methods vary between sources, the numbers below should be considered approximate.

First World Hotel Leads the Global Ranking

Malaysia’s First World Hotel occupies the top position with approximately 7,351 rooms.

Located within the Genting Highlands resort area, the enormous property is part of a much larger entertainment and tourism destination. Its scale allows it to accommodate visitors in numbers that would be difficult for most conventional hotels to handle.

Its position demonstrates how integrated tourism resorts have transformed the concept of a hotel, combining accommodation with entertainment and other visitor facilities.

Las Vegas Remains the Home of Mega-Resorts

The United States has an especially strong presence in the ranking, largely because of the enormous integrated resorts found in Las Vegas.

The Venetian Resort is listed with approximately 7,264 rooms, placing it just behind First World Hotel.

The resort is known for combining hotel accommodation with casino facilities, retail areas, restaurants and entertainment attractions. Its large room inventory reflects the scale of Las Vegas’ convention and tourism industry.

Several other Las Vegas properties also appear among the world’s largest hotels.

Saudi Arabia and Macau Feature Prominently

The Clock Towers complex in Saudi Arabia is reported to have around 6,000 rooms, putting it among the largest hospitality developments globally.

Macau’s The Londoner Macao is also listed at approximately 6,000 rooms. The property is part of Macau’s extensive integrated-resort industry, where hotels are combined with entertainment, shopping, dining and gaming facilities.

Another Macau property, Sheraton Grand Macao, appears in the ranking with approximately 4,001 rooms.

Russia’s Massive Hotel Complexes

Russia is represented by two exceptionally large properties.

The Izmailovo Hotel in Moscow is listed with approximately 5,000 rooms. Its large capacity has made it one of the most recognizable mega-hotel complexes in the country.

Another major property, Barkhatnye Sezony, is reported to have around 4,688 rooms. Located in the resort region of Sochi, the complex reflects the scale of accommodation developed around major tourism destinations.

MGM Grand Among the World’s Biggest

The MGM Grand Las Vegas has approximately 4,762 rooms, placing it among the largest individual hotel properties by room count.

Its huge accommodation capacity is supported by extensive entertainment, dining, convention and casino facilities, making the property a major destination in its own right.

The same approximate room count is reported for the Wynn Las Vegas and Encore resort complex.

Mandalay Bay and Luxor Continue the Las Vegas Presence

Two more famous Las Vegas resorts also rank highly.

Mandalay Bay Resort and Casino is reported to have approximately 4,426 rooms, while Luxor Hotel & Casino has around 4,407 rooms.

These properties demonstrate how Las Vegas developed a distinctive hospitality model based on very large integrated resorts rather than conventional standalone hotels.

Thailand’s Ambassador City Jomtien

Thailand’s Ambassador City Jomtien is another major property on the list, with approximately 4,219 rooms.

Situated in the Pattaya area, the resort has been designed to accommodate large numbers of visitors and groups. Its scale places it well above most conventional hotels in terms of accommodation capacity.

ARIA and Sheraton Grand Macao

ARIA Resort & Casino in Las Vegas has approximately 4,004 rooms, while Sheraton Grand Macao is listed at around 4,001 rooms.

Although they are located in different markets, both properties demonstrate the importance of integrated resorts in driving large-scale hotel development.

Other Major Hotels in the Top 20

The remaining properties include several internationally recognized hotels.

Excalibur Hotel & Casino has approximately 3,981 rooms, followed by Caesars Palace with around 3,970 rooms.

Bellagio has approximately 3,933 rooms, while Circus Circus Las Vegas is reported at around 3,773 rooms.

Japan’s Shinagawa Prince Hotel has approximately 3,680 rooms, making it one of the largest hotel properties in Asia outside the resort markets of Southeast Asia and Macau.

The list is completed by Paris Las Vegas, with approximately 3,672 rooms, and Fontainebleau Las Vegas, with around 3,644 rooms.

Why Are These Hotels So Large?

The enormous size of these properties is closely connected to the development of integrated tourism destinations.

Large resorts can combine thousands of hotel rooms with casinos, restaurants, shopping centres, entertainment venues, convention facilities, swimming pools and other attractions. This model allows visitors to spend much of their trip within a single complex.

Las Vegas has particularly embraced this concept because of its enormous visitor and convention economy.

Other mega-hotels have developed around pilgrimage tourism, international tourism, large-scale entertainment and resort destinations.

A Hotel Can Become a Destination

A conventional hotel primarily provides accommodation for travellers. Mega-hotels operate differently.

With several thousand rooms, such properties require extensive staffing, food supplies, transportation systems, security operations, housekeeping networks and technical infrastructure.

Some of the world’s largest hotels can accommodate more guests than the population of a small town.

This scale creates significant logistical challenges but also allows operators to offer a wide range of services under one roof.

Room Counts Can Change

The ranking should not be treated as a permanent global leaderboard.

Hotels renovate, expand, close rooms, merge towers or change the way their accommodation inventory is reported. Some sources also count connected buildings or multiple hotel towers differently.

For that reason, room numbers can vary between publicly available databases and individual hotel information.

Nevertheless, the list provides a useful picture of the extraordinary scale reached by the global hospitality industry.

The Future of Mega-Hotels

The continued development of integrated resorts suggests that mega-hotels will remain an important part of international tourism.

As destinations compete for tourists, convention visitors and large events, enormous accommodation complexes can provide the infrastructure required to host visitors at scale.

From Malaysia’s Genting Highlands to the casinos of Las Vegas, the resorts of Macau and the major tourism centres of Russia and Thailand, these properties demonstrate how the modern hotel has evolved into something much larger than a place to sleep.

With thousands of rooms under one roof, the world’s largest hotels are effectively self-contained tourism destinations, combining accommodation, entertainment, dining and commerce on a scale rarely seen elsewhere in the hospitality industry.
