Solo cause you can do and go to places as per your wishes the only drawback is no one to click your pictures but other than that its the bestttt
Take bike. Move for NCR highways . Stop at dhabba. Eat pranthas with chai. Enjoy best part of your solo trip
More exploring can be done on a solo trip but a trip with friends is more enjoyable tbh
Trip wid friends is like a cherry on cake.
If it's about now then trip with frnds ( much needed!!)
But otherwise a solo trip is a must in the entire lifetime
You get to know so much about yourself its just a blissful experience
Definitely a trip with friends!
