Does someone know for sure how the ticketing will work? Because I think I know how I would imagine Universal would set it up.
Will there be an exit at each station from the park, so that anyone can board the train? That way one day tickets will just get off at the IoA side and loop back around and ride it back, and two park tickets will be able to get off at IoA. That, or tickets will be checked at the station (by a conductor of course) and one-day tickets will have designated seating that they will not get up from once the train reaches the other park. I can see that working out alright
