U: Hi, I need to locate a train to Leicester that will arrive by 16:45.

S: Okay we can do that. Where are you departing from?

U: Leaving from Cambridge this coming Thursday.

S: You have several choices. Trains leave Cambridge at 5:21, 6:21, 7:21, 8:21, and 9:21.  The 9:21 arrives at 11:06. Shall I book one of these ?

U: OK I need one that arrives at 15:45 and I will need the travel time and the train ID.

S: The closest I have to that is a train arriving at 15:06  and takes  105 minutes to arrive. The train ID for this journey is TR1160. Would you like a reservation?

U: No, I don't need a reservation.

S: Is there anything that I may help you with today?

U: Yes, I was also looking for a place to stay somewhere in the north.

S: sure, what price range?

U: In the moderate price range, please.

S: I'm trying to narrow 11 choices down.  Would you want free parking or free internet?

U: free parking, please.

S: How about Archway House in the north? It has free parking and free Internet. It gets 4 stars. Would you like to book this one?

U: Is this place quiet?
S: The rooms are very quite which is normally appreciated by the customers but also at times there is loud and disrupting noise which rarely occurs.
