I read tons of travel guides before visiting Polar Ocean Park, but none of them were helpful. Arriving at 8:30 a.m., it was packed. The ticket gates really need to be improved. There's no separate flow for those who buy tickets at the gate, which significantly delays entry. The lines were incredibly annoying. Everything we could see indoors was blurry, and the animals were cute, but we needed to see them through the crowds. We were thinking of exploring the outdoor area first before heading back inside, just briefly enjoying the Ferris wheel and the sea lion show. It was so hot, the performers and the sea lions were working really hard, and we, the spectators, felt a bit disappointed that the ride was so short and too hot. Also, it's best to sit in the middle section, as the actors are there to see the show. Even the front rows on the sides didn't offer much. The 5D ride and story are outdated, making them only suitable for younger children. Adults and children in third grade and up shouldn't queue. After the outdoor area, you can't go back inside directly; you have to queue through the main entrance. My child didn't want to wait in line, so we didn't experience it. I wonder if we'll let him do it again.
