Tickets are sent via email. You can change the time of your visit at any time. When you get there, just scan the QR code to scan the ticket. No need to print it. Very convenient. Recommended for Harry Potter fans. The event is the best. It's like you're really in the movie scene. The replicas, the atmosphere, the music are excellent. Plus, you can use a magic wand to cast spells. I like that you can stay in each room for as long as you want. But if you change rooms, you can't go back to the old room. So take pictures and clips until you're satisfied before changing rooms.
