I am looking for a cheap place to stay in the east part of town.
No problem. We have 3 guesthouses that match that. Do you have a further preference?
I would like one that it relatively cheap and located in the east part of town. 
Well, there's the Autumn House, would you like to give that a try?
Is that a 4-star place? I would like a 4-star place, even though I need it to be cheap.
Yes, the Autumn House is a cheap, 4 star guesthouse. Free wifi and parking are included. Would you like me to make a booking for you?
Yes, can I get the postcode, and also I am looking for a train that departs from Cambridge and arrives at Kings Lynn as well.
The postcode for the autumn house is cb58rs.  There are 133 trains travelling from Cambridge to kings lynn. Could you be more specific on what day/time you're looking for?
The train should leave Monday after 17:45.
Trains run every hour from 18:11 all the way to 23:11. If you don't have a preference, perhaps I can book you the 18:11 train? It arrives at 18:58.
Yes, go ahead and book 4 tickets for me on that train! Once that is done, can I have the reference number?
Booking was successful, the total fee is 39.2 GBP payable at the station. Reference number is : Y9FTRIGK. Is there anything else I can help with?
nope that is all thanks
No problem. Enjoy your time in Cambridge!
