My only concern, and from the beginning, is the size. It looks TIGHT. So does Diagon though, so ill see how this plays out. Gotta hope with Mario Kart, the gaming, Yoshi, dining, and shop (shops?) that this is able to spread the crowds out. While id impinge the queues for Yoshi and MK are large, if they ever overflow the building and crowd into the land its going to be really tough to navigate imo. Im sure these are all factors they have thought of however, I mean we all are aware that the MK queue can hold tons of people so thats good.
Other than that, it looks literally perfect. Having an awful day so this was just what I needed!
