Personally, I think they should have just let the 2 Park pass holders ride the HE. First, it eliminates this "re-ride" problem, which will most likely cause confusion and problems. What if someone dislikes the ride (it makes them sick, perhaps) and does not want to ride back?. Second, it helps keep capacity and chaos to a much smaller scale, and finally it gives an extra incentive to purchase the 2 day ticket. It seems like a smart business decision to allow people that pay a bit more, get access to more. no?
