What have you got on the west side, in the way of places to stay offering free wifi?
I have two guesthouses and two hotels. Any preference?
That doesn't matter to me but I do want to make sure I stay somewhere with free parking.
I would recommend the Cambridge Belfry Hotel.  It is 4 stars and has excellent ratings.  Would you like more information?
Yes, could you tell me the postcode and the price range?
The Cambridge Belfry post code is cb236bw and it is fairly cheap compared to other hotels in the area.
That would be fine. I also need a train that leaves after 21:30 on wednesday. 
I'd be happy to help. Where are you traveling to?
I will go to London's Kings Crossing from Cambridge. 
I have only found 1 train from Cambridge to London Kings Cross on Wednesday.  It leaves at 23:00.  Will that work?
That would be just fine can you book that for 6 people?
Your reservation for 6 on the TR7942 train was successful, the total fee is 141.6 GBP payable at the station. Your Reference number is : 4SU5FYGN.
Thank you! That's all I need. Goodbye. 
You're very welcome! Goodbye!
