After Hawa mahal, you should go to palace. Half of the palace is residence of the Royal family and half is for tourists. The tickets are relatively expensive and so called complimentary photos are a actually a scam to charge extra. But overall it's okay kind of experience.
Near by they have a handloom shop store managed by cooperative society. It's nice place to buy some sarees, dupattas, stoles, and kurtas. Price is fixed and quiet reasonable. Have some shoping and go to jal mahal. you can just watch it from the road side.
