Ever since it was announced, fans of the classic video game have been salivating at the prospect of getting involved in their own madcap motoring experience, and while the coronavirus pandemic has put paid to our chances of visiting in the immediate future, we can still add it to the list for future travel, right?
Guests have finally been allowed into the park to experience what it is like, and some of them made a beeline straight for the Mario Kart: Koopa's Challenge ride to show us what to expect.
Basically, it's like a gigantic virtual version of the Nintendo game, which sounds awesome to begin with.
The racers sit in their life-sized Mario Kart vehicles and race along some bits of the most popular tracks from the game while wearing augmented reality goggles.
Some seriously impressive looking effects allow you to perform all the tricks and traps that you'd expect, such as throwing shells around the track and hampering your opponents by taking them out of the game.
Obviously, it's quite hard to translate the AR experience into something you can watch on YouTube, but we can still get a decent idea as to what it will be like whenever Nintendo fans from this side of the world are allowed to travel to the park.
Four riders occupy each race, and each has their own vehicle. The track itself is a composite of a load of popular courses and features elements from the underwater level, as well as fan favourites like Bowser's Castle and the ever-popular - or infuriating - Rainbow Road.
If Mario Kart isn't your bag, there's a lot more on offer at the park than that.
For the wee children there's Yoshi's Adventure, where visitors climb onto Yoshi's back and attempt a treasure hunt to catch the Golden Egg.
If you're not a Nintendo fan, that last sentence - and much of this article - probably made less than no sense.
Moreover, the whole park is an interactive experience. Visitors can buy Power-Up bands that they can use for challenges around the park, playing mini games and punching blocks to collect coins and find hidden Easter eggs knocking about.
It looks incredible and is certain to appeal to the kid in anyone, whether they're a Nintendo fan or not.
