Penglai or Qingdao Ocean Polar World, which is more fun? Friends who have been there, please tell me.

90 yuan (bought from the travel agency) is the ticket for Penglai, but it costs about 170 yuan after all the sightseeing. It's too dark. There are many places that charge extra. Unlike Qingdao, it is accessible. Penglai is the best in the world, but it is not as good as Qingdao on the whole. There are automatic elevators in Qingdao, and it is very expensive to go to Penglai and the price is not clearly marked, so it is difficult to bargain. After all, it is a county-level city, unlike all the scenic spots in Tai 'an, which are clearly marked and not very expensive. In addition, children's tickets in Penglai Scenic Area are 1. 1 meter full price. Is it dark? All the scenic spots in Penglai are around 400 yuan. Go to Qingdao. Qingdao is a metropolis after all.
