I'm looking for a hotel with free parking, can you help me out?
Do you have a preference on a hotel or guesthouse? 
I don't have preference on type of place, but it should have 4 stars.
Do you have a preference for location or price range?
No, I'm not worried about those things, just as long as it has 4 star, free parking, and doesn't need to include Internet.
How about the Acorn Guest House? It meets your criteria and is on the North side of town.
That sounds great. Could I get the postal code, please?
Sure! The postal code is cd41da. Would you like to make a reservation?
I also need a train from Cambridge.
And when are you wanting to depart from Cambridge? 
I'm sorry, I mispoke, I need a train to cambridge. I need to leave ely after 08:30 on thursday. 
I have train TR2029 that will depart Ely at 09:35 and arrive in Cambridge by 09:52. Would this schedule interest you? 
Perfect. I'll need a booking for 4 people.
Your tickets are reserved. The reference number is 7DX9JIIE. The cost is 17.60 GBP payable at the station. Can I help you with anything else?
That should be it, thanks!
My pleasure! Enjoy your stay!
