I flew in with my aunt to celebrate my birthday.
We could have bought the official group-buying price for two people, but since my aunt is eligible for a senior citizen ticket, it wasn't possible for just one person. So we had to find a group-buying deal on Xianyu (a second-hand marketplace app). Everyone there was a single person, so we paired up. The scalpers made a little profit, and we paid less. However, we needed to enter as a group at a designated time in the morning, using the group entrance, which was still relatively fast. So I recommend it to those buying solo tickets.
I initially thought Saturday would be crowded, but the scalpers said weekends are the least crowded because the park also hosts spring and autumn outings. Later, I saw that was indeed the case; the queues for almost every ride were manageable.
If it's your first time here, you'll have a great time. There are many marine animals to see, and many electric rides have almost no queues. There's also the scariest parrot roller coaster in China—I bravely went on it!
In the evening, there's a water fireworks show and a drone show, making it an incredibly happy birthday night.
The food in the park is a bit pricey, but the portions are large and the food is quite good.
