Q: Are there any thrill rides in the theme park, such as rollercoasters, dedicated to any of the characters? A: Yes, there will be thrill rides, there will be very intense thrill rides, there will be immersive, engaging rides that are filled with story and fantasy, and there will be lots of opportunity for people to get different entertainment experiences that are based on characters. SC: I think it’s very important that the theme park represents the entire saga, from book 1 to book 7. It needs to feel complete, and it will feel complete.
