Is it possible of Haridwar - Badrinath - New Delhi trip in 4 days by going alone?

Hi folks,


Actually I want to make a trip of Haridwar – Badrinath – New Delhi. I have only 4 complete days ( 15th , 16th, 17th, 18th of August) and I should be back to Delhi on 19th of August. Can I make the trip comfortably in 4 days? Moreover I want to stay overnight in Badrinath. Is it possible?. I am not going in a group. I am going alone. Is it Possible. And is it more expensive if I go alone. I am not going to spend any time in Haridwar or Rishikesh since I already had a visit in both places.
Could anyone please guide me with proper travel plan and the places to visit according my availablity of time. Can I get proper transportation other than Govt.buses (Like Cars or Travera..... etc.).

Note: I am starting at NewDelhi on 14th Midnight at 23:45 and I will reach Haridwar on 15th of August at 4.30AM. So my source is Haridwar. ie. Haridwar - Badrinath - Delhi

Plz help me in this regard. Its more important to me

Thanks in Advance.
