Hi Preet, if you like to travel to beaches then prefer going to Pondy or Gokarna. Both the places are amazing. Gokarna is mostly like a place where you go and do nothing and close to Gokarna there is Shimoga which is beautiful place. Pondy is one where you go take a beer sit at beach and mostly the cultural heritage is amazing. I can say both the places you can stay not more than 4 days. On the other hand Ooty and Coorg are hill stations. I don't know how Coorg is after the floods recently. But it's a beautiful place and so is Ooty. But these places are also for like 4 days one's.
There are other places like Wayanad, Hampi, Munnar, Kodaikanal, Mangalore etc., close by
