Woman: Journey
Man: We use this when we talk about going from one particular place to another. A journey can be long, or short but repeated. For example:
Woman: My journey to work is a nightmare with all the road works.
Woman: I went on a lovely train journey through Italy last year.

Woman: Trip
Man: We often use trip when we are thinking about the whole visit (including your stay in a place and your journey there and back). A trip may be short, i.e. a day trip, or longer, i.e. a trip around the world, and can be for business or pleasure. Listen to these two examples:
Woman: Shall we go on a shopping trip to London?
Woman: I’ve got to go on a business trip to New York.

Woman: Excursion
Man: This is a short organised trip you go on with a group of people. For example:
Woman: We went to England last year, and went on a full-day excursion of London on an open-top double-decker bus, it was wonderful.
Woman: My daughter’s gone on an excursion with her school to visit Etna.

Woman: Now you will listen to a conversation between two people planning a trip to Rome

Woman: I’m so excited! I’ve never been to Rome before, are you sure you can get the time off work for this trip?
Man: Yes, we can leave Thursday evening and come back on Monday afternoon.
Woman: Thursday evening? But, I didn’t think there were any evening flights to Rome.
Man: I thought we could take the train over night.
Woman: Isn’t it a long journey by train, It takes at least 8 hours.
Man: It does, but, we can sleep on the train and arrive in Rome early in the morning, that way we’ll have more time to explore Rome. We can travel back by plane if you like?
Woman: Okay then that sounds fine! What are we going to do there? You know Rome so well.
Man: Well, as it’s your first trip to Rome I’ve booked you on a VIP excursion on Saturday, so you’ll get to see all the sights in one go. Then we can return to anything that you really like.
Woman: That’s fantastic!
