The first day I would build
Give the city one clear route before adding extras.
- Start with People's Park and Roxas Night Market while energy is high.
- Use Davao Crocodile Park as the natural reset instead of crossing town too early.
the easier plan is People's Park and central food first, Roxas Night Market later, Samal or Eden Nature Park as a separate day. 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 Eden Nature Park just because it looked close on a map.
