The first day I would build
Give the city one clear route before adding extras.
- Start with Hailing Island and Dajiao Bay while energy is high.
- Use Maritime Silk Road Museum as the natural reset instead of crossing town too early.
the easier plan is Hailing Island and Dajiao Bay first, Maritime Silk Road Museum nearby, Jiangcheng for practical stops. That keeps the day readable instead of turning every good name into a separate detour.
I would rather leave one place for tomorrow than drag a tired route through Jiangcheng just because it looked close on a map.
