Hi, Can you help me find a train from Norwich to Cambridge?
I would be happy to help! What day would you like to travel?
I would like to arrive wednesday at 16:45.
There is a train which departs at 15:16 and arrives at 16:35 would you like me to book that one?
No need to book it today.  I would like the price and travel time if you have it there, though. 
The price is 17.60 pounds and travel time is 79 minutes. Can I assist you with anything else today?
I also need a hotel with free parking. 
We have 29 hotels that may be what you need. Is there a certain area or price range you are looking for perhaps?
I'd like a guesthouse with a star of 4, please.
The archway house meets your criteria. Do you need help with booking?
Yes please, I need it for 4 people, 3 nights starting on Wednesday. 
Unfortunately, that length of stay is not available. Would you like to try again for a shorter stay? 
How about 1 night at the archway house for 4 people.  Please book and provide a reference number.  Thank you.
Booking was successful.
Reference number is : FEK7TT66. Is there anything else?

That's all I needed today, thank you
Thank you for contacting us, have a nice day.
