The first day I would build
Give the city one clear route before adding extras.
- Start with Meenakshi Amman Temple and Thirumalai Nayakkar Palace while energy is high.
- Use Gandhi Memorial Museum as the natural reset instead of crossing town too early.
the easier plan is Meenakshi Temple first, Thirumalai Nayakkar Palace next, markets or Gandhi Museum when heat and timing allow. 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 Vandiyur Mariamman Teppakulam just because it looked close on a map.
