Let me tell you about this convention centre which goes by the name:
“Sri Seetha Ramula Kalyana Mandapam”
It is located in a small village in AP, India, called “Veerlapalem”.
It is basically a hall with all the facilities like electric points to connect lights, fans, etc.
It is an open-to-use hall for anyone.
It is not perfect. It does have those pesky little shortcomings like the lack of a parking area within its premises, like in the basement or something.
Due to this, all the cars need to be parked somewhere along the road or on the premises of the nearby temple.
The local language is Telugu(India) and they are friendly enough to guide you through the procedure of booking, and other formalities.
