Road trip - Delhi to Kasol

Simla?

The route is Karnal-Ambala-Zirakpur-Pinjore-Nalagarh-Swarghat-Bilaspur-Mandi-Pandoh-Kullu / Bhuntar - Kasol.

Hey, I am leaving for kasol on the night of the 1st September and expect to reach Kasol by 6 AM the next morning. I am driving a Maruti Ritz and 3 my friends (1 male & 2 Females) would be travelling with me.We plan to visit Tosh and some other places near Kasol which can be reached by road (No Trekking). I believe that there's a road that goes to Tosh from Kasol and I am a bit worried as to how the condition of the road is? I am very well acquainted to mountain driving, but still I am worried about the width of the road and the possibilities of Landslides. I would like to request some suggestions for nearby places which we can cover as a part of our day trip..Also are there any good accomodation/cafe options in Tosh? We plan to set base in Kasol but can amend our plans if theres places like Kasol around Parvati Valley.

Thanks
