I'm impressed to see Universal Parks & Resorts be number three behind Disney and Merlin in terms of attendance. As far as I can tell, they only operate five parks (plus a water park), compared to Disney's 12 and Merlin's 16. Then again, all those parks lie near the top of their respective continents' attendance lists. Pretty massive attendance per park, in other words! The only Universal park that doesn't pull more than three times as many visitors as Merlin's top park is Universal Studios Singapore, with 4.4 million visitors compared to Gardaland's 2.6 million (and yes, it surprised me too that Gardaland is the most visited Merlin park). I guess good theming, good rides, strong IPs and great locations help.
It also surprised to see the great difference in visitors between the top-tier parks in North America and those just behind. Okay, the two most visited parks are in a league of their own with 20 and 18 million visitors, but then there are seven parks at 9-12.5 million visitors. And then the tenth most visited park is all the way down at 4 million, then the ten next parks on the list are between 3 and 4 million. Really surprising that there are no parks with annual attendance numbers of 4.1 to 8.9 million, when there are nine parks above that gap and eleven just below it.
