OM GOVINDA Y NAMAH. I would like to advice the people who are going to Tirupathi and Tirumala. Dont ever become VICTIMS of Fraud travel agencies.
Go only by ITDC buses.
Dont ever go by Private buses. you will end up with paying unexpected amount. They create lot of trouble. They charge extra in between the journey. They take yo to some other places and charge high amount. You might have paid only 600 for them. But you will end up paying more than 1500 or 2000 rupees sometimes. They will change you to walk a lot or catch an auto to go another location. They may stop the trip in the middle, telling that vehicle is in trouble, AC is in problem. This is from my experience. Just take this as an advice from a beloved devotee of VENKATESWARA.
Assume that you are the only one who has to be dropped to one location. They will try to get down you in some location near to their station.
NEVER EVER GO BY PRIVATE BUSES. GO By ITDC or APSRTC or KSRTC buses only....
