I am planning for a mid-term traveling (for around 15-20 days) in South India covering parts from AP,Kerala and Karnataka only, along with my family members. Now the problem is nobody from my family ...
Sources seem to differ on what precautions are required. Is there an authoritative source I can check, or is it better to drug-up anyway (or not to)?
I am planning to drive down from Bangalore to Chennai? Which is the best route to take? How much toll do I need to pay?
