We are also planning trip end of july. Room rates I got for couple of hotels and demanchi which is a good place to stay rate is 9000rs per night and they accommodate 3 people in a room. I stayed there in october 2015. We were 5 and they forced us to take 2 rooms instead of 1. Not sure if someone is good in bargaining can make some good deal maybe. Hotel millennium quoted 12000 for a room for july.
Jeep rates would be at least 5000 in season as per my knowledge. October 2015 we gave 3000 though it was off season but it was a long weekend so many people were there. 2000 for jeep I believe is off season rates.
So keep in mind all rates will be high in july and as many people go to naran now so hotel owners might not even like to bargain much.
