To be honest, the theoretical capacity might actually turn out to be decent. The time between block clearance (last car of the lift/last car of the final brakerun) is about 30 seconds, which can result in close to 120 dispatches per hour. 120*16 = 1,920pph, which is actuall insane for such a small ride. Even with more realistic 45 second dispatches (hoping that they can do their work on Europapark level), we are still talking of numbers north of 1,400pph.
Sure, this is on the lower end of what a Disney coaster should provide, but it is still a suprisnigly high number.
So this ride seems to be extremely dependend on the staff.
