I vaguely remember hearing that it’s shorter only by one foot, but I’d say that the brakes make it feel shorter, as you glide out into the splashdown and smoothly slow down, while in Orlando, with no brakes, you feel every bit of the speed from that drop when you crash into the water. There’s an easy to find vid of Hollywood’s JP on YouTube from 1997 before the brakes were added, and if you watch that, you’ll see that the drop seems bigger when you keep all that speed after flattening out into the splashdown
