Hello I need to go to Cambridge and will be leaving on Saturday from Norwich, can you tell me what my train options are?
There are many options. Is there a certain time you would like to leave?
Yes, I would like to depart any time after 20:15.
There is a train departing Norwich at 21:16 on Saturday. Would this be ok?
Yes.  Can you give me the train ID and the travel time?
The train ID is TR3267 and the travel time is 79 minutes. Is there anything else I can help you with or would you like to purchase tickets?
I would also like to book a 4 star Guesthouse
Okay I have found several options. Is there a particular area you want to stay in?
Yes, I'd like something in the north, and in the moderate price range, please.
Acorn Guest House is a really nice 4 star place.  Free internet and parking too.  Can I get you more information?
I need to book it for 6 people and 4 nights starting from the same day. 
I was able to book your stay at the Acorn Guest House. Your reference number is SW8AC8GH.
Thank you! That's all I needed.
Great. If you think of anything else feel free to ask any time.
