Bhai don't go to naran in eid holidays, it'll be jam packed. You won't enjoy. If u must need to go, dont stay at naran rather stay at batakundi. but rates will be sky high. the normal room will be available at least 6000 to 7000 per night. prior booking wont work. they are not of their's baaaps in peak season...
You can travel till Naran in your corolla. the road is newly paved. just be cautious while descending. always descend on gear and not on breaks. your corolla will take care of the rest... Wassalam, Junaid
