gogo !! google translate bro! it can read to!
Reading, listening and then speaking, that's how i learned English
Learning the grammar structure of the language is the most important thing, then memorizing as much vocabulary as you can (start learning the most used common words first). After that, everything else will become a lot easier, like reading/listening.
But since it seems you need to learn the language as fast as possible for travel reasons. I would put A LOT of focus on "Listening".
You can always find a way to make yourself understand in some way, like pointing in a map or hand gestures,etc. But if you can't understand what ppl are saying to you, you are pretty much fucked.
