Hi, I'm looking for a guesthouse in Cambridge.
I have found 24 guesthouses in cambridge. Is there a particular area you are wanting to stay in?
I don't care but it needs to be cheap.
Okay, the allenbell is a cheap guesthouse, would you like me to make a booking?
Does it have free parking and internet?  Also, I'd like to be in the centre of town.
Yes it does and it in the east though, is that going to be problem?
Yes, I need one that is in the centre. Please give me the postcode, price range and star of the hotel. 
I have the Alexander Bed and Breakfast guesthouse available in the centre. It's cheap, 4 stars, with free wifi and parking. It's in postcode cb12de. Would that work for you?
Yes thank you. I also needs a train on tuesday that arrives by 16:15.
What is your departure and destination locations?
I would like to depart from kings lynn and go to cambridge. 
We have 11 trains matching your request. Was there a specific time you wanted to depart?
Whichever one gets me to Cambridge closest to 16:15.
TR8932 will arrive at 15:58 would that work for you?
Wonderful, could I just have the price for now? I may book myself later. 
The price per ticket on TR8932 is 9.8 GBP. Will that be all?
Yes, thank you so much! Goodbye!
