S: The latest train you can take is the 18:24 train out of stansted, which arrives in cambridge at 18:52. Would you like took book a seat?

U: No, but could you give me the train ID, departure time, and travel time of that train?

S: Certainly, the train ID is TR5433 and it departs at 18:24.  The total travel time is 28 minutes. Can I help with anything else?

U: I am also looking for a hotel. I would like it to be a four star that includes wi-fi.

S: We have 21 hotels of that type. Is there a location or price range you would prefer?

U: Actually, I'd like the hotel to include free parking if possible, but it doesn't need to have free wifi. I'd like to stay on the north end of town.

S: Would you like to stay at the worth house? It's a guesthouse in the north, in the cheap price range, has 4 stars, wifi and parking.

U: Is that hotel in an area that is preferred by lots of people?
S: It is preferred for its amazing location, that is central and close to many different types of activities. Anything else you would like to know?
