Which South India Tour Package Covers Temples and Kerala Backwaters?

I'm planning a trip to South India and looking for recommendations on the best South India Tour Packages.

I am particularly interested in:

✔️ Ancient temples in Tamil Nadu
✔️ Cultural heritage sites
✔️ Kerala houseboat experiences
✔️ Nature and wildlife attractions

I've come across options such as the 12 Days South India Temple Tour, 12 Days Tamil Nadu with Kerala Tour, and South India Tour with Kerala Backwater.

Has anyone recently traveled on a South India Cultural Tour? Which itinerary would you recommend for first-time visitors?
