Can you help me find a train departing from cambridge going to stevenage?
What day would you like to leave?
I would like to leave after 16:15 on tuesday.
I have a train that laeves at 17:21. Will that do?
there is none that leaves earlier? how much will that one cost me?
There is no earlier train. The price is 12.80 pounds.
Okay thank you. Could you help me find a guesthouse in the centre to stay at?
I have 2 guesthouses in the center. They're both cheap, but the 4-star Alexander B&B is by far the better choice. Would you like to book a room?
I need one in the expensive price range that includes free parking.
I'm sorry we don't have an expensive guesthouse in the centre area. Would you like to try some different criteria? 
Ok, well do you mind trying to see if there is a hotel that matches my other requests. 
I recommend University Arms hotel. I meets your criteria. Would you like me to book you a room?
Yes, please. I would like it for Thursday for 7 people, 5 nights. 
Your booking was successful.  Your reference number is : VH6MRHBA.  What else can I help you with today? 
Thanks, that's all. Goodbye
