Definitely don't worry about the language issues. Bring a phrasebook wherever you're going and you'll be fine. Just act apologetic when you don't understand something or when you reveal that you don't speak the language. When I was living in Europe for work, I spent a weekend in Zurich and ended up at a restaurant where we absolutely couldn't speak to our waitress. Between myself and the people we were with, we knew English, French, and had a German phrasebook. After answering no to English and French, we asked about German, and she said no. Unfortunately we realized later that we'd used the French word for German, so it was no surprise that she said no! Anyhow, just through some crazy gesturing we still managed to make it through the meal and even the poor waitress was cheerful about it!
