I have 3 kids (6, 3, 3) and my oldest is likely to want to ride some rides that my younger ones won't want to. So for Space Mountain, I should only get 2 fastpasses for that ride. 1 for me, 1 for my son. Once he rides the ride, then we can do a rider switch he can ride again with my wife. So this would be like receiving 2x the fastpasses? Is that correct?
