I'm looking for a train.  I need to leave from Cambridge on Tuesday and go to Leicester.
Do you have a time that you would like to leave by or arrive by? 
Yes, I need to arrive by 8:45.
TR2950 will arrive at 08:06, would that work for you?
Yes, can I get 6 tickets please and I'll need the reference number too
 the total fee is 226.8 GBP payable at the station and the reference number is : XYAOCTIY. May i help you with anything else.
I am also looking for a place to stay that has 4 stars and is in the centre.
We have two choices, alexander bed and breakfast which is in the cheap prince range and university arms hotel whic is in this expensive price range.
I do need free wifi included, so whichever of those has wifi is the best! 
Actually, they both do offer free wifi and free parking. Alexander bed and breakfast is a guesthouse and the University Arms hotel is a hotel type. Do you have preference?
I'd prefer a hotel. Can you book that for 6 people and 3 nights?
Which day would you like to check in?
Starting saturday, either place is fine if available.  
The booking did not go through, can you book another day or a shorter stay?
Yes, could you try for a stay of 1 night?
I was able to make a reservation for Saturday night at University Arms Hotel for 6 people. Your reference number is 7XXHIROP. Is there anything else you need today?
That is all I need.  Thank you for your help!  Goodbye!
Thank you for contacting Cambridge TownInfo centre. Goodbye!
