I planned the trip late (i.e. 3 weeks ahead). Because of car problems, my friend and I arrived just before midnight. Not only was the desk attendant waiting for us, but he had the room open, with the AC turned on!
But when we entered the room, life got unexpectedly better. I had requested a twin room with 2 beds... we were given 2 adjoining rooms, each with its own bath, but charged only for the twin room!!!! The rooms were immaculate with comfortable beds (not the "boards" of most Indian beds). Everything was clean and fresh.
The pool is small but lovely. Breakfast buffet was very good (and even when we arrived late, the staff accommodated us with more scrambled eggs, fruit,etc), and the dinner offerings were not only the buffet, but we were able to order off the lunch menu.
On our last evening, we met the daughter of the owner, and she helped us locate an ayurvedic medicine shop.
Overall, my experience with Dera Rawatsar was outstanding. I will return next time I go to Jaipur.
