Seeking Advice for Madurai Trip: Cab Hire or Cheaper Travel Options?

Hi all, I'm planning a trip to Madurai with my family (parents, brother, and me – 4 people) from 20th to 23rd December. We'll be arriving in Madurai on the 20th and need to be back in Bangalore by the 23rd. We want to explore Madurai and possibly include Kanyakumari in the itinerary if time permits. I'm considering hiring a cab for the entire trip for convenience, but I'm open to other suggestions if there’s a more cost-effective way to enjoy the journey. Would love recommendations on: Reliable cab services in Madurai for multi-day trips. Cheaper or alternative travel options for covering Madurai and Kanyakumari. Must-visit spots along this route. Any tips for making the most of this trip with family. Thanks in advance for your help!
