Christmas is not celebrated in India, of course, unless you belong to the minority community, of whom there are quite a few in Kerala but not so many here in Tamil Nadu. So we basically skip it today.
Proceed on to Mahabalipuram (1/half hr drive). Mahabalipuram is on the seashore, city of 7 pagodas and is the 7th century seaport of the Pallava empire. On arrival checked at the unremarkable and definitely not so "ideal" Ideal Resort Hotel.
