Pros: The venue is huge, integrating four attractions: a water park, marine animal shows, a beach, and an amusement park. All four are top-notch, allowing you to play all day without getting bored.
There's plenty of food, and it's not too expensive. Besides instant noodles and self-heating hot pot, you can bring food with you.
The sea lion and dolphin shows were great, but I cried. I wonder what kind of training these animals go through to perform so spectacularly. I can't overthink it...
The Ferris wheel was very stable, and my first Ferris wheel experience was a big plus...
The rafting and children's rides were both great, I loved them.
Complaints/Tips: The facilities are average. For example, there are several changing rooms and bag storage areas, and restrooms are everywhere, but first-time visitors don't ask for directions and often head for the one closest to the main gate. The changing rooms are equally sized for boys and girls, but the girls' section is clearly undersized. I waited in line for nearly half an hour on a hot day. Once inside, there were only hooks and a trash can—not even a stool—making changing extremely inconvenient. The lockers are 40 yuan a day. There's also an outdoor storage area further inside, but I'm not sure how much it costs.
The shower heads only work when you're standing upright, and the water only flows for a few seconds. Then you have to hold your head up with foam to find the sensor. It's so annoying... Also, bring your own toiletries; there shouldn't be any shared ones. There were so many people inside that several benches were cluttered with stuff, making it hard to see clearly...
