For those that don't know, I'm a huge rollercoaster junkie, and know a lot about them and different manufactures of coasters. It usually is tradition that the first people to ride or test a rollercoaster are the very ones who built it. My guess is that it is people from WDI, Vekoma, or construction workers. Being that this is Disney, I could be wrong but that's my guess. One thing is for sure though...whoever they are, they are darn lucky and just made me jealous!
