Traveling alone means you rely on you to get around - translator apps are okay in some circumstances, but you can't have the phone stuck to your face the whole time. Being "forced" to really pay attention to your surroundings is a good thing. Words become familiar surprisingly fast, and there's a great sense of accomplishment in ferreting out the meaning for yourself.
