For Legoland, I specially came to Nagoya. There was a 92% discount on buying tickets on Trip.com, which was cheaper than other platforms. You don't need to change tickets, you can directly brush the QR code to enter the park. The day I went was the New Year holiday in Japan, and there were many people. However, the queue is still acceptable, the longest time to take a roller coaster took an hour. Others are in half an hour. For children under 10 years old, Legoland is more suitable than Universal Studios.
