Wich is the best attraction for kids in SHANGHAI? How do I get there by bus?Ill have 12 h in the city

Hi, you can take your kid to Ocean Aquarium. By taking Mglev to Longyang Raod, where transfer to local subway line 2 to Lujiazui MTR Station. Then you can walk aorund 200m to the attraction. After visiting, you can have a visit at local famous Nanjing Road Pedestrian.

Happy Valley can be your second choice, but it is around 68km from PVG (maybe your transit is at PVG?). Anyway, take shuttle bus line 3 to Dapu Rd and walk to Dapuqiao MTR Station to take subway line 9 and get off at Sheshan Station. Then cross the street to take the shuttle bus to Happy Valley directly.
