I'm looking for a train leaving on Sunday that is going to Cambridge.
There are 200 trains coming to Cambridge on Sunday. Is there a particular time or departure location you're interested in?
I want to depart from london kings cross after 13:30.
Sure, the first train leaves at 15:17. Would you like to book it?
No, I would like to book at a later time, but can I please get the train ID?
Sure, the 15:17 train's id is TR7931.  Is there anything else I can help you with?
I am also looking for a place to stay. I would like the hotel to have free parking and free wifi.
My listings show almost 30 separate lodgings around town with free wifi and parking! Do you have any other preferences to help me pick one for you? 
Yes, I would like a guesthouse with a 0 star rating.
There is city centre north b and b, and el shaddai which would you like to book?
El Shaddai sounds fine. I need to reserve it for two adults for two nights, please.
Alright, what day will you be staying?
Sunday.  Could you please send me the reference number?
Unfortunately the booking was unsuccessful. Would you like me to book it for another day or duration?
How about just one night instead? May I have the reference number please?
Great, that was a successful booking, the reference number is  9H97D0MB. Is there anything else I can help with?
No that's all, thanks! 
You are very welcome. Enjoy your stay!
