This is a review for the IMAX theatre.
I would say that this what you call a real IMAX theatre vs the converted AMC ones you see in LA that are not as big as the normal IMAX. Sound is loud- but comfortable loud and not blaring. Also, the seats are comfy and recline. I would say to get there 30 minutes early so you have a good angle on the screen on opening weekends. I loved it - and thought that it was well worth the price of admission. If I had to see a movie in Vegas - this is my choice of theatre.
