The first day I would build
Give the city one clear route before adding extras.
- Start with Hassan II Mosque and Habous Quarter while energy is high.
- Use Old Medina as the natural reset instead of crossing town too early.
the easier plan is Hassan II Mosque first, Habous or Old Medina next, Corniche later if the day needs sea air. 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 Place Mohammed V just because it looked close on a map.
