Hi. I am looking for a train going to Cambridge on Thursday. Can you help me?
Train TR2775 departs from london kings cross.
No, I need a train that departs from stansted airport and it should leave after 11:30.
The first train to Cambridge from the airport after 11:30 is TR9775, leaving at 12:24 and arriving in Cambridge at 12:52. Will that work?
I think so. What exactly is the travel time on that one?
The travel time on that route is 28 minutes. Is there anything else I can help you with? 
I'm also looking for a particular hotel. The name is Leverton house.
Would you like me to make a booking for you?
Please. I'd like a room for myself, I'll be checking in on thursday and would like to stay for two days.
I'm sorry but I was unable to book that hotel with your exact details. Would you like to book on another day or for a shorter stay?
Okay, try for one night instead please.
Booking was successful for Thursday for one night. Your reference number is : GMAAU9LE. Can I help you with anything else today?
No, you have been a great help.  Thank you and goodbye!
Thank you, and please remember you can contact us at any time if you need any further assistance! Have a great day!
