Since you are getting off the train at Ajmer, it is obviously good to invest the day visiting Pushkar and Ajmer both. It will consume the entire day. Sri Nathdwara is close to Udaipur and in case you intend visit there you should go straight to Udaipur and not Ajmer. You simply cannot cover these places in just one day.

Osiyan is on the way to Jaisalmer from Jodhpur at approx. 60km.. it has got an ancient temple of Sri Sanchiya Mata and has good activities near by just in case you don't have time for Jaisalmer

hot air balloon we could not see in pushkar. wrt desert stay, there is no desert in pushkar ( as we see in movies ). if you want to experience real desert, then Thar is the place. for this you need to travel to Jaislmer. it is about 600km from Pushkar/Jaipur

Avoid Pushkar. Except for its religious value there is noting much there. Try Chittorgadh it is much better. The fort is also great and well maintained.

The cities have developed rapidly and the city cleanliness systems are being developed. Villages are very clean because there is hardly any waste. Everything is recycled and reused. Intensive awareness drives are required.

Yes it is available, but you need to ask the local person there, no signage is given there.

2 hours Jaipur to Ajmer .you may stay in pushkar as it is very sooting and calm place and visit Ajmer in 1-2 hrs it hardly takes 20-30 minutes from pushkar to Ajmer .

ajmer is famous for dargah sharif and pushkar. one can visit round the year pushkar is just 20kms from ajmer and easily accesable by govt buses and autorickshaws and private taxis.. very economical place for staying and eating. ajmer dargah sharif mosque darshan is must visit bramha temple in pushkar is a must visit and a holy bath in sarovar. can be done in a one day visit one can enjoy camel ride at pushkar..but i recommend not to do a camel ride...because the persons vendors charge very high there and are very rude and they treat the tourist like nothing if one wants to visit the sand by walking.. they not allow to enter the sand area ..no restrictions are by goverment to enter.. but these persons are goondas..and behave like they had purchased the land ...if one tries to negotiate a camel ride or enter the sand by walking they beat the tourist and have a bad treatment give bad words..they dont see if a family is with you or females ladies are with you. this should be stopped and informed to rajhastan govt and police..strict actions should be taken so that this goondagiri can be stopped here by the govt and police.
