Still one of the world's most vibrant cities despite astronomical living costs, it's no surprise London is the world's second most visited destination.
So what's the first?
The emphatic answer, says market researcher Euromonitor International, is Hong Kong.
Attracting an impressive 27.77 million international tourists in the space of a year, the Asian city outstripped London's popularity to the tune of 10 million people.
The influx, chiefly accounted for by mainland Chinese visitors, kept Hong Kong at the forefront of Euromonitor's annual Top 100 City Destinations survey for the fifth year in succession.
London, which last crowned the list in 2009, pulled in a mere 17.38 million, just ahead of Singapore at 17.09 million.
Euromonitor's list is compiled from data from 57 "core" countries, using national statistics and info from airports, hotels and other tourism industry sources.
The company says the latest figures, from 2014, show geopolitical tensions and successful marketing campaigns swaying tourist decisions.
But despite fluctuating fortunes for some key destinations, it says tourism remains an upward trend with all but a few cities improving on visitor numbers.
That said, Euromonitor warns of interesting times ahead for some of the main players.
Once again, Hong Kong outstrips the competition, attracting 10 million visitors more than its nearest rival. The city welcomed 27.77 million international visitors in 2014.
It says Hong Kong's reliance on Chinese tourists is a weakness as their increasing affluence takes them further afield — a situation likely to be exacerbated by recent protests there against mainland Chinese travelers.
London is Europe's biggest draw for international tourist arrivals, welcoming 17.38 million in 2014.
London's expensive reputation and the fact that its airports are nearing capacity could also see it losing out to European rivals, Euromonitor says.
With 17.09 million international visitors, Singapore was the third most visited city on the list.
As for Singapore, "limited natural attractions" and a reputation as a business rather than leisure destination could see it struggle to "remain relevant" against low-cost alternatives like Thailand.
Political troubles have dented Bangkok's popularity. It received 16.25 million visitors, down 7 percent in the previous year, causing it to drop from third to fourth ranking.
The City of Light held on to the No. 5 ranking, despite a 1.9 percent decline in visitor numbers to 14.98 million.
The casinos and theme parks that give Macau its nickname of the Las Vegas of the East have doubtless helped push it into the number six slot. The city drew in 14.97 million visitors.
In the 1980s it was just a small town in southern China. Today Shenzhen is an economic powerhouse that in 2014 welcomed 13.1 million international visitors.
North America's top draw was New York, with 12.23 million international tourist arrivals.
Istanbul, currently ranked ninth, is identified by Euromonitor as "one to watch."
It says the city could build on a year-on-year increase of 13.2 percent although the emergent threat of ISIS could prove challenging.
Better known globally than Antalya, Istanbul welcomed 11.87 million international visitors in 2014.
Kuala Lumpur, Malaysia
Tenth-ranked Kuala Lumpur saw 11.63 million visitors, making it the sixth-ranked Asian city.
Antalya, a Mediterranean resort town in southwest Turkey, saw 11.5 million international arrivals in 2014. Antalya is a magnet for Russian visitors. The ancient amphitheater of Aspendos is about an hour east of the city in Antalya province.
Dubai, United Arab Emirates
Dubai is the Middle East's leader in arrivals, and its popularity seems to be increasing in step with the city's rapid expansion. It attracted 11.39 million in 2014, up 8.9 percent from 2013.
Seoul welcomed 9.39 million international visitors in 2014. Perhaps the leap of 8.9% on the previous year was helped by pop star Psy's blockbuster homage to the city's swankiest neighborhood, " Gangnam Style."
Perennial European crowd-pleaser Rome ranked 14th, with 8.78 million international arrivals.
Taipei's National Palace Museum is one of the world's largest. The city itself pulled in 8.6 million visitors.
At 16, the southern Chinese metropolis of Guangzhou had 8.2 million international visitors.
Unlike Pattaya, Thai coastal paradise Phuket managed to increase its visitor numbers — up 1 percent to 8.1 million. That didn't stop it slipping two places on the previous year's ranking though.
Miami Beach boasts the world's largest number of Art Deco buildings. It's one of the attractions that helped lure 7.26 million international tourists.
The Thai beach resort town of Pattaya holds steady at number 19 on the chart, despite an 8 percent drop in visitor numbers to 6.43 million.
