The journey would be by car. I'm usually a solo traveller. Space available only for co-passenger (1 person) 

I'm a frequent traveler and there would be about 15-20 destinations that would be covered in tamilnadu. It's not a fixed route places may get added also might get removed from the list. 
Experienced from years together with the route from roads to stay and in any help from locals that can also be taken care.
