For maximum impact, here's something I noticed:
I always ride SM in the front seat, but after my first 2 rides this morning, I decided to try the view from the back. Other than the lift hill projections (which work great from the front seat), I think most of the projections have a bit more impact if you are back a couple rows. Also, since several play along the walls on the outside of the curves, sitting on the left side of the car will put them right beside you. (Don't say I didn't warn you...)
