I once waited in line for the Great Movie Ride for 2 hours when the park first opened. I was there like a month later. It was that or the first backstage tour.
I would recommend Mears but if you are getting in late I would go with something else.
My family and I got in one trip at 11pm and by the time Mears picked us up and all the stops we did not check in until after 1 in the morning.
