I am going to be staying in north cambridge and need a hotel, I can pay for parking. 
Ashley hotel is available.
Oh, I have heard of that.  Is in in the North part of town?  I am looking for a place in the moderate price range also.
Yes is it moderate and in the North side of town. Would you like to book there? 
Sure, that seems fine.
Ok.  What day would you like to book for?
Before you book, I just want to make sure--does it have a 4 star rating?
No, it is a two star hotel. Could you recheck and restate your perimeters to me?
How many stars, area, and price.
It's in the north, moderately priced and has a 2 star rating.
No, I'm sorry, I should have specified. I need a 4 star place to stay.
I'm sorry. I don't have anything that matches your preferences. 
Are you sure? I need a 4-star, moderately-priced hotel in the North part of town, and I don't need free parking.
Again nothing, I could search again but doubt that a new hotel was constructed there during the last couple minutes.  Are you open to a guesthouse or different area?
I'm definitely open to a guesthouse.
do you need free internet?
Doesn't matter if it does to me.
We do have some. The acorn guest house is quite nice, when are you planning your stay?
Well I would just need the postcode. Sorry for all the confusion !
The acorn guest house postcode is cb41da.
Thanks. Are there any cinemas around the guest house?
No there is not. Would you like me to check in a different area?
What about something to do with boats? 
There is riverboat georgina would you like the address and phone number? The entrance fee isn't listed. 
Great, I will also need a taxi to leave the hotel by 20:15. I will need the car type and contact number.
Okay I have booked you a taxi and your contact number is 07925606670 and they will be driving a black Toyota.
Have a nice day.
Thank you, you too.
