I will grant my initial ride on Gringott's I was a little disappointed that it wasn't more of a coaster, but I think it is still done well. It feels like a suped up version of Transformers/Spider-Man. It is still a lot of fun and feels very technoligcally advanced. And the queue is amazing. The bank lobby is one of my favorites spots in the park.
I really enjoy Space Mountain but it feels very basic in comparison. The queue is pretty bland but does fit the theme so don't want to say it's bad, but it's just not as engaging. The ride experience I love but it is a basic family coaster just setting in a dark room.
