Hello anand. The same situation happens with most of us. As ur budget is limited it is advisable for you to travel to Delhi from Hyd via train. Later you can opt for local transport. And also dont book hotels in advance as this is a off season you can find plenty of home stays at lesser costs.
Hey Anand, if this question is pertaining to a trip that you have enquired from Tripoto, then just drop a mail to info@tripoto.com ... They will reply you with answers ... Happy Travelling Bro!!!
