Arrive a bit early to avoid a long queue. Luckily, there weren't many people that day, so there wasn't much waiting to enter any of the rides. Booking was easy; just show the QR code and you can enter and receive your privileges. It was very convenient. You can bring a selfie stick in Hong Kong, and most importantly, a power bank, because you'll be taking photos until your battery runs out. It was so much fun!
