I need a train departing from cambridge after 17:45.
Ok. There are lots of options. Where would you like to go?
I'd like to go to Norwich on Monday.
TR6688 leaves Cambridge at 8:36 for Norwich. Would you like to book this train now?
Nah, thanks though. But if ya can tell me when it gets there that'd be good. 
I'm sorry TR6688 departs Cambridge at 18:36 and arrives in Norwich by 19:55. 
Great. I'm also looking for a 3 star hotel with free parking.
We have five hotels matching those requirements. Do you have a preference for area or price range?
I'm looking for something moderately priced please.
There are three choices in that price range: Bridge Guest House in the south, Hamilton Lodge in the north, and Hobson's House in the west.
Let's try the Hobson's House please. 
Ok. Do you need me to book that for you?
Yeah, could you book me a 3 night stay at Hobson's House?
When would you like to book your stay?
Friday. For 7 people. 
That hotel isn't available for 3 nights? Are you able to shorten your stay?
How about one night?
The hotel has been booked for you for Friday night for a total of 1 night for 7 people. The reference number is RJEXYUD1.
Great! Thank you so much for all your help.
It is our pleasure. Have a great day!
