I am planning to travel for 3 weeks around Argentina, I plan to arrive and depart from Buenos Aires. I am not booking all my accommodation/travel ahead of time, as some of the distances are so vast, I don't know exactly where I will be ahead of time.
How practical is this considering I don't speak Spanish?
My assumption is, that learning the usual basic words, hand gestures, persistence and a bit of research ahead of time would suffice, is this unrealistic?
