We'd like to make a day trip to La Plata by commuter bus.
I understand that we catch buses at the bus station near Retiro train station. Also that we can catch the 129 in Av 9 de Julio. Is there a stop near Obelisco? Directions appreciated.
Most important question How do we pay for tickets?
We have used coin-only ticket machines on local buses for short trips. Can't imagine having enough coins to pay for the much longer trip to La Plata.
We speak no Spanish and have managed so far to communicate with bus drivers by pointing to our destination on a street map or by handing driver a piece of paper with our destination written on it. And smiling a lot as we say "Gracias".
Appreciate your help.
