U: Are there any trains going to cambridge from kings cross?

S: There are several. What is your departure day and time?

U: My departure day is Monday at 15:45.

S: The closest train I have leaves at 15:17 and arrives at 16:08. Would you like me to book this for you?

U: Yes, please. Can I get the travel time and departure time first?

S: Train TR9114 leaves at 15:17 and is a trip duration of 51 minutes. Do you want me to book it?

U: Oh, no, I see that train will not work for me. I need to arrive by 15:45, not depart by it. I'm sorry. Could you find me another?

S: I have train TR3194 that departs at 13:17 and arrives at 14:08. Would that train be better for you?

U: Yes, that would work better. Can you tell me how long the travel time is?

S: The travel time is 51 minutes.

U: Wonderful, thanks. I am also looking for a place to stay in the north. I'd like free wifi as well.

S: Of course! I have a dozen hotels that meet your needs. What type of place are you looking for? A certain price range or star rating, perhaps?

U: Yes, I am looking for a 4 star hotel that includes free parking and wifi.

S: The acorn guest house meets this criteria. Should we book something?

U: Do they have stable internet connection?
S: The internet connection at the Acorn Guest House is said to be super fast. Do you want me to go ahead and book a room for you?
