I am planning a trip in Cambridge.
Do you want to stay in a certain area?
No,I am actually looking for information about trains going from Cambridge to Norwich on Sunday.
There are 19 trains available on that day. Do you have a departure or arrival time in mind?
Arrive by 11:30.  
I'd recommend TR4969. It arrives by 10:55. Would you like a ticket?
Yes, please book 3 tickets.
I have booked 3 tickets on TR4969. Your reference number is MPL4USAC and the total fee is 42.24, payable at the station. Can I assist you with anything else?
Great I'm also looking for a place to stay in the expensive price range with free parking.
What area of town could you like the hotel to be located?
I would lkle to stay In the north please.
There are none with that criteria in the North. Shall I change or try another area?
Could you try a cheap one then?
