Before I travel, I always write down common questions and sayings on index cards in the native language to make communication easier. Write the questions or sayings in the country’s native language on one side and on the side, write the English translation. (This way, you don’t accidentally ask the taxi driver where the ladies room is.)
Things you should include on your card include asking about bathrooms, police, hotels, and any other issues you think you may face. Also, be sure to write down your allergies, medical conditions, and medications.
