Those that will interest me, I would say. But normally the basics.
Like where can I buy food? How much is this? Where's the rest room? How do I go to the hotel? Help. Nice to meet you. How are you?
and many more :)

Always good to know a few useful phrases. AND of course, being able to understand the ANSWERS.
