Hi, I need a train that departs from cambridge.  I need to leave after 15:00.
There are many trains that depart Cambridge at that time, what day do you need the train and where are you going?  
i am going to peterborough on tuesday. 
I have 18 trains available.  What time would you like to arrive?
I would like to arrive by 18:00 if possible. 
I have train TR6357 that leaves at 17:06 and arrives in Peterborough at 17:56. Would that work for you?
Thanks.  I also need a place to stay.  Can you find a guesthouse with free parking?
Would you like me to book the train? There are 21 guesthouses that offer free parking do you have an area you'd like to stay or price range? 
I'll deal with the train, thank you.  I want a fancy expensive guesthouse, does that narrow it down any?
I have no expensive guesthouses in Cambridge. Is there another price range you would be willing to accommodate?
Please try for something in the cheap price range.
There are many guest houses that fit this criteria, do you wish to stay in a certain area?
I don't know the area. Can you suggest something for me?
The Alexander Bed and Breakfast is lovely.  Would you like me to reserve rooms for you?
Yes for Sunday for 3 nights for 3 people please.
Booking was successful. Reference number is : MS9KDSFF. Is there anything else I can help with ?

I hope you have a great trip.
