If you plan in a right way, and take train for traveling, you can visit "Dehradun, Rishikesh, Haridwar"; "Jammu and Vaishno Devi trip"; and "Shimla" for 3 days.
I'd travelled all these three localities with 4 members of my family in just 20-25k for each trip.
It would take 1 and a half hour to reach Mussoriee from Dehradun from bus and would cost around INR 45-60. However if price is not a major concern you can go for taxi for a more comfortable trip and that would cost you between INR1000-1200 , shared taxis can cost you a bit cheaper though.
Hello Vikram , I'll be happy to answer your travel queries from my experience βΊοΈ.
*The route you mensioned are totally opposite and from different different states , Mussoorie and auli are from uttrakhand and kufri ,Shimla ,Rohtang are from Himachal Pradesh .
*you can do only once at a time .whether you can explore uttrakhand by Mussoorie to auli route covering kedarkantha, joshimath , Rishikesh or you can travel to himachal-pradesh by this route ,delhi Shimla-kufri-manali-rohtang-dalhausie-dharmashala and back .
*since you mensioned that you are planning for bike trip ,I would suggest you to better explore Himachal this is because due to early infrastructural development,it has better roadways and transportation facilities than uttrakhand .
*you can go through this link to book good hotels in himachal ,I just checked online and the best deals were at tripoto itself.
