Go for some trekkihg or camping..this is the best thing to experience with friends better than any other outing..trek in nature,explore nature..kheerganga is gud option
If you like beaches or party kind of guy then obviously Goa. If you like adventure then rishikesh and of you like to do trekking then Triund trek would be best.
Har ki Dun & Kedarnath are not the destinations to chill unless you are capable of completing treks of 28kms & 12 kms easily. If you wanna chill, go to places like goa, pune, alibag or Mandi, in Himachal. Stay at property like Simply Shimla: The Kothi In SHimla and chill. https://www.tripoto.com/trip/where-to-stay-at-shimla-the-kothi-5cae395cd6bf9
