If you look back at any blog or forum talking about Nintendo Theme Park rides from before the Nintendo x Universal partnership was announced, they all very consistently had the same few ideas. Mario Kart, DKC Mine Cart rollercoaster, maybe a Metroid or Star Fox shoot-em-up ride cause it was the 2000s, and Pokemon Snap. Despite a lack of high sales for that specific Pokemon sub-series, Pokemon Snap is a very popular and appealing ride idea that goes back just as far as the rides we ended up getting for Super Mario Land.
Both the N64 and Switch Pokemon Snap games are essentially designed like theme park attractions to begin with. It is the exact perfect concept for a project like this. I can only hope they don't overthink it.
