I'm looking for a place to stay.  Can you help me find one?
What area of town would you prefer? 
I would like to stay in the north. Wi-fi and at least four star reviews are also important.
That narrowed it down a bit. Do you have a preference on the price range? or the type of accommodation?
Not really, no. Can you give me the phone number for your favorite place?
Acorn guest house , the phone number is 01223353888.
Thanks, I also need to train form broxbourne to cambridge on sunday.
What time would you like to depart?
Depart does not matter but I need it to arrive by 12:45. 
I have train TR6774 that leaves at 10:32 and arrives in Cambridge by 11:32. Will that work for you? 
Sounds like it.  What is that travel time exactly?
60 minutes is the length of the train ride
Thanks. That's all I need. Good-bye.
Thanks and enjoy !
