I need a train leaving after 8:15 going to stevenage.
Is that leaving from cambridge? What day would you like to leave?
Yes, I'm leaving from Cambridge on Wednesday.
TR8913 will leave at 9:21 and arrive by 10:10. Do you want to book a seat? It will cost 12.80 pounds.
No that is all I need for now.
Do you need help with anything else? Hotel, attraction, etc?
Yes, a place to stay/  I am treating myself so make it an expensive one with free parking. 
Can you tell me what area you would like to stay in please?
Any area would work. It needs to be a 2 star hotel.
The Express by Holiday Inn Cambridge meets your description. Would you like to make a booking?
Yes, please book it for me.
I'd be happy to help. Is it just you, or will you have other guests? And for how many days will you be staying?
I do not want to book  it. I just need the postcode. 
Their postcode is cb13lh. Can I help with anything else?
That's all I needed.
Ok great, have a fantastic day!
