Hi, Considering if you are starting from Delhi, You can plan your trip in following order of cities. Delhi - Jaipur - Jodhpur - Mount Abu- Udaipur - Ajmer - Pushkar You can book your stays in Jaipur, Jodhpur, Udaipur and Pushkar at Zostel or at any bag packing hostel.
The stay for each day will be approx 500-600 only. Also you can plan for 10 days which will give you enough buffer time for travel and rest. Jaipur and Jaisalmer you can plan for 2 day each. And for rest you can plan for single day if you wish to cover only the famous spots.
