For the best ride on RnR, do NOT sit in the front cars. This ride accelerates so fast that your eyes do not have time to adjust to the initial strobe lights. DH always gets a terrible headache if we sit in the front car, so we always opt to sit in the last car or two, even if we have to wait. You'll get a much better ride from the rear cars as your eyes have that extra split second (and I DO mean split second!) before entrance into the ride.
