Hi Arjun I would definitely suggest Kerala. You can explore the backwaters, the beaches and the tea estates here. Here is a guide to help you plan your holiday. https://www.tripoto.com/kerala. Happy Travels!
November and December are great months to visit any of the tourist places in South India whether you are planning a trip to the beach, hill or just a casual visit to the city as the weather would be really great. Only thing hotel price is bit higher due to peak. Goa, Coorg, Pondicherry, Mahabalipuram, Kovalam, Ooty, Munnar, Alleppey, Chikmagalur, Yercaud, Kanyakumari, Rameshwaram, Malpe are the few to names.
