The place I liked most is Blue street lanes of Jodhpur which is very near to Mehrangarh Fort. Other than that must see places are Mehrangarh Fort, Jaswant Thada, Umaid Bhawan Palace and Toorji ka Jhalra step well which is best at morning time. Hope it helps.
In the morning head towards umaid bhawan palace, then to toorji ka jhalra..most picturesque location in Jodhpur.. dn by walking go to Mehrangarh fort...then to jaswant thada n end the Jodhpur trip...nothing else to see
