Give you a reference: Haichang Ocean Park played at 9~ at 19 o'clock on the first day, and 9~ at 15:30 on the second day. All the performances in all venues did not fall (except for the children's height limit 1.2 meters of rafting), so it is necessary to stay in a resort hotel for one night, which is very convenient. Many strategies do not have actual performance time, I recorded: killer whale 25min, mermaid fairy tale 10min, walrus 15min, dolphin 20min, beluga love 15min, fantasy sea 25min, 4D cinema 15min, sky screen cinema 10min, cable car 3min. As far as the queue is concerned, the rafting is at least 2h (we queued up to say height limit, children crying), the killer whale is at least 1h, and other popular performances are queued 40min in advance. Time efficiency is well controlled by yourself. If you can, it is recommended to stay for one night and play for 2 days, people will not be too tired.
