Assisted travel is not only for people with walking difficulties and it costs nothing extra.
After our day on the hop on/hop off bus to visit San Cristóbal Hill and the Bicentennial Memorial Park, we had just a morning to do a bit more exploring of Santiago.
We finally got to bed at about 03:00 after flying in from Panama but were up in time to enjoy breakfast.
Getting from Panama City to Santiago in Chile turned out to be a very long day.
