I'm looking for a place to stay in the north.
Acorn guest house is in the north, would that work for you?
Yes if it has free parking, meals, pool and wifi. I want it to be in the expensive price range.
I'm sorry, there are no expensive hotels in the north area. Acorn Guest House is moderately priced, and does have free parking and wifi. Would you be interested?
I am looking for a hotel in the north part of town with free parking, a 2 star rating, and in the moderate price range.
How about Ashley Hotel in the north part of town? It's on Chesterton Road. 
Sounds good.  Can you book it for four nights starting on Tuesday?
No, I am sorry another day perhaps or a shorter stay might be able to get that booked for you.
Can we try it for 1 night?
Booking was successful. Your reference number is NTQSJSP0. Do you need further assistance today?
Yes. I need a train from Ely to Cambridge.
The trains departs from Ely every two hours at 5:52, 7:52 so on. What time do you plan to travel?
I need to be in cambridge by 21:45. Could you find me close to that time?
And which day would you like to leave on?
I would like to leave on Tuesday please, can I have the price and depature times also?
Your best bet would be TR1537 which arrives in Cambridge at 19:52.  The price is 4.40 pounds per ticket and the departure time is 19:35.
That is all I need. Thank you.
