The Dirtiest Las Vegas Hotels

With delicious food, lively nightlife, iconic residencies and world-famous casinos, it’s no surprise that Las Vegas manages to attract millions of visitors each year. 

Luckily for these visitors, Vegas is also home to some of the most beautiful resorts and hotels in America.

However, the team here at VegasInsider wanted to identify which of these hotels have been committing the most sins when it came to their cleanliness. 

Using Tripadvisor reviews for 30 of the most famous hotels on the iconic strip, we ranked each hotel on the percentage of terrible-average (1 to 3 star) reviews which included words associated with uncleanliness.

Top 10 Dirtiest Vegas Hotels

The top 10 dirtiest hotels based on our data are as follows:

The STRAT Hotel, Casino & Tower only has 291 Tripadvisor reviews. But when we looked at the terrible-average reviews, we saw that nearly 28% of guests had something negative to say about the hotel’s cleanliness, thus making it the dirtiest hotel in our study.

With over 20% of guests complaining about the cleanliness level, Circus Circus ranks as the second dirtiest hotel in Las Vegas. The hotel, which boasts the world’s largest permanent circus, had a whopping 951 bad reviews mentioning the word ‘dirty’, meanwhile 901 negative reviews also mentioned the word ‘smell’. 

Excalibur Hotel & Casino, Flamingo and Las Vegas Hilton at Resorts World rounded off the top five dirtiest hotels in the study. When looking at the Flamingo in particular, the hotel had the most negative reviews which mentioned the following words – awful, garbage, dust, filthy, gross, mess and nasty. 

Top 10 Cleanest Vegas Hotels

Fortunately for those hopeful of visiting “The Sin City” soon, there are hotels that seem to be on the cleaner side. According to our data, the top 10 cleanest hotels in Las Vegas are as follows:

Taking the crown as the cleanest hotel in Las Vegas is the Four Seasons Hotel, which is also home to the most expensive penthouse in the city, according to another study. Only 1.13% of one-star to three-star reviews for the hotel mentioned words associated with uncleanliness. 

When it comes to spotlessness, the Wynn Hotel doesn’t seem to be at risk of losing customers with very few reviews mentioning hygiene levels. Closely following the Wynn was NoMad Las Vegas which is located at the top of the Park MGM. 

The Venetian was also ranked in the top ten cleanest hotels, and it was joined by its sister property in The Palazzo, which actually finished one spot higher in the rankings. 

We think you can't go wrong with these clean hotels when you're traveling for a fun time in Las Vegas!

Our Methodology

We gathered 30 of the most well-known Las Vegas hotels to operate in and around the Las Vegas Strip. 

Using Tripadvisor, we then looked at how many terrible-average (1 to 3 star) reviews for each of these hotels mentioned terms associated with uncleanliness or bad hygiene. 

Each hotel’s terrible-average reviews mentioning the negative terms were then divided by the hotel’s total reviews and multiplied by 100 to give a percentage.

This percentage was used to rank the hotels from dirtiest to cleanest based on the frequency of cleanliness complaints.

All data correct as of February 2025.
