Hello Friends! My 12 yr old son rode this ride for the first time in October and is now a fan and has delved into learning as much as he can about the ride. He is trying to figure out how many elevator cars are operating at any given time in the ride _ I guess the maximum that can go and how they'd cycle through the 4 load zones and 2 drop shafts. He knows there are 8 Elevator "cars" in all but we cannot figure out how many are running and how. Any help would be a blessing! Merci!!
