Booked an adult ticket and two half-price tickets for the elderly. There is no text message to confirm the ID card and other information, so I can only enter the park with a try. As a result, the staff took an ID card once and showed 1 adult ticket; Take another ID card, showing 2 half-price tickets, and entered the park smoothly. All worries are redundant. It is really convenient to book tickets here. I will book here next time.
