I had never seen the Polar Express so this was a new experience all around. I’m not sure how long they will be showing this at Sea World. If I were just rating Polar Express, then it will get 4.5 stars. Without giving anything away, I want to say that I wasn’t particularly impressed with the 4D aspect. Basically on top of the 3D that you get to experience, they through in things like wind, water, smell and other elements to make you feel like you’re actually there. Cool in theory, but I think more could have been done. Nonetheless, a great place to take the kids. Remember this is 3 stars and not 2 or less. I did enjoy the experience, but it just didn’t wow me.
