Teaching English in a short time

I teach English in Japan to mostly kindergarten kids, but one of my student's parents would like to take a crash course in English for 30 days because he's traveling to the States. He wants to learn the most essential parts of English and I'm trying to piece together themes that are important.

So far I've thought of asking for directions, going to the restaurant, shopping, transportation (airplanes, trains, taxis, at the train station, airport, etc.)... anything else? What would be important for someone who hasn't learned English but needs to speak it?

I'd also make sure he's familiar with traffic signs (though you probably have that covered under transportation already)
