Having been sidelined by work I'm late in my planning for end of December/January 1) I will have spent a night in Vellore, 2 nights in Mahabalipuram. I then want to go south to Pondicherry. Can this be done by train?
2) I would like to spend a half day walking about the Rajagiri and krishnagiri at Gingee. I plan to visit Thiruvannamalai. Are these best done as day trips from Pondicherry? If so should I then spend 3 or 4 nights in P'cherry? Or fewer nights In P'cherry and one or two nights in Thiruavannamalai?
4) Where would it make sense to hire a hiring a driver for a few days?
I hope this isn't too much to ask in a forum. I'd appreciate some thoughts if only to parts of this. Thanks.
