The mario kart ride is certainly going to divide opinions!

====================================
From watching the POV it's certainly less coaster and more physical sets than I was expecting! I was surprised at how much stuff they'd actually made real, I was assuming the AR would be carrying a lot and leaning more towards VR but it's really well integrated with the sets. You could easily ride this without the glasses and still have a passable experience no worse than some regional dark rides The Magikoopa corridor is a favourite, although the AR kinda masks a lot of it!
It's slower than I thought, but the projections and AR will certainly make it seem a lot faster than it really is. The projections are well done and, aside from the obvious screens, fairly subtle. The rainbow road floor looks particularly swish and I adore the way the winner glides almost seamlessly between the AR glasses and the projection screen beyond at the end of the ride.
Got to say that going for a tracked ride based on mario kart seems an odd choice given the trackless masterpieces we've seen elsewhere?

Overall the area looks really nice, the powerbands are a really interesting idea especially with locations all round the area to collect points.
