Both should still be operating. The Studio Tour will close a couple of hours before park closing, so I'd keep an eye out for that. WaterWorld normally has a few evening showings during peak season, so you should be okay there too. You can check the show guide for the showtimes.Okay so I'm planning on going this Saturday night, but I won't get there until around 5:45 pm. Will the tram tour and Waterworld show still be operating since the park is open until 10 pm? I've been wanting to do both of those so bad in the dark!
