Dalian Railway Station-Shengya Ocean World: Take bus 16, 22, 23, 406, 53 1, 90 1 and get off at the Second Hospital of Medical University, just across the road. (It takes about 10 minutes to take a taxi, and the fare is about 19 yuan).

Official website shows:

One-way ticket to Shengya

Shengya SeaWorld 1 10 yuan/person (half-price: 55 yuan)

80 yuan/person (half-ticket: 40 yuan) in Sanya Polar World.

Shengya Coral World 50 yuan (Half Ticket: 25 yuan)

I bought a group ticket online, Ocean World+Polar World+Coral World ***96 yuan, but I have to pick it up near the train station. Fortunately, it's not far.
