We're doing Universal for two days so I bought park-to-park for both days so we could ride Hogwart's Express. First day is at IOA with Express tickets because we like rides. Second day is at Universal Studios without Express. I bought the park entrance tickets from Undercover Tourist site and the Express tickets from the Universal site. Hoping when I present all my paper tickets and ID at the gate, they just give us each one card for the Express ticket? Or do we have to present something at each ride to get into the fast lane? Thanks
