As you mentioned that you are from kolkata then i'll suggest to move out for Sikkim(Gangtok,Yumthanng Valley,Namchi, Khangchendzonga National Park), for Assam(Kaziranga, Manas National Park, Haflong, Majuli), Peoples of there are sweet and places you'll definetly love it. Even there are many places in West Bengal(Darjeeling, Sundarbans,Jalpaiguri,Kalimpang)to spent good time with your friends and if you'll move for orissa then there are also good places like Chilika Lake,Puri Beach,Daringbadi.
It depends on where you are from, Which state you wish to visit and also your budget.
If you give details about states you are keen on visiting probably we can help you out better.
Since I am from the south for us Ooty, Goa, Munnar, Wayanad, Kodai are a few options to consider here.
