The first day I would build
Give the city one clear route before adding extras.
- Start with Marudhamalai Temple and Perur Pateeswarar Temple while energy is high.
- Use Gedee Car Museum as the natural reset instead of crossing town too early.
the easier plan is Perur or Marudhamalai first, food and textile shopping nearby, hill transfers kept separate. 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 Brookefields Mall just because it looked close on a map.
