You can go To Goa;I visited the goa in Dec 2015.The beaches are decorated like a bride.At that time;the famous Sunburn festival also get organized there.You can go to cruise for the parties.And away from the beaches is peaceful,clean,less crowded area i.e. South Goa.Hire A scooty and wander all tha goa with the help of google maps.In other options;you can go to Jaiselmar and Rann of Kutch. Or if u want to see the snowfall go to Shimla or Manali.
In Himachal You can go to 1)Trithan Valley 2)Parvati Valley 3)Manali 4) Shimla 5)Macleodganj 6)Spiti valley.

But Due to flood problem;HP and Uttrakhand are out of options until the news come.You can go to North Sikkim;it is untouched heaven on earth.Darjelling is not as good as much it is hyped.
