I have been to Tirumala and Tirupati thrice in my life time and both the cities are beautiful, well-maintained, neat and clean and this is due to the TTD, a NGO body which looks after the cities.
TTD had constructed rooms for devotees and provides them at cheaper, affordable prices and I got the privilege to stay at Vishnu Nivasam at Tirupati which is equipped with all the necessary facilities for the devotees.
TTD even provides free meals for the devotees and the management also manages and provides Darshnam of deity for the devotees in a very systematic manner.
The transportation system is world class and TTD provides special bus service from 5AM to 5PM every day for the devotees.
TTD provides all the above discussed facilities and even more at affordable or free of cost for the devotees and I’m very impressed by their approach
