I need a place to stay in Cambridge that includes free wifi. I don't need free parking.
Would you like to try cityroomz?  I can book it for you?
Is it in the West? what is the price range?
Cityroomz is moderately priced and in the centre. Are you open to places that offer free parking, or do you specifically want to avoid it?
I'm open to it, and I suppose the centre will do. But I'd prefer the west side if there is one.
I'm so sorry.  There are no hotels on the west side that match your requests.  
That's okay, Cityroomz will work. Can you book it for 3 people for 2 nights starting on Tuesday?
Reference number is : Z9RFJQ4W. Anything else you need?
Yes I am looking for a Train that departs from Cambridge and arrives at Birmingham New Street. 
Ok.  When were  you looking to leave?
I will be leaving on Wednesday after 14:30.
There are 9 trains listed. Would you like tickets for one of them?
Yes. Please select the first train available after 14:30 and book 3 tickets. then provide me the reference number
Booking was successful, the total fee is 225.3 GBP payable at the station. Reference number is : XMBOA4E1. Can I help with anything else?
That is all for now. Thank you
