I need train schedule information for Thursdays, please
I can help with that. From where are you departing and to where are you going? 
departing from cambridge and arrive by 21:45
There are 168 trains that day. Do you have a destination in mind so I can narrow it down?
I need to go to stansted airport please
I would recommend train TR7966 that leaves at 05:40
That's fine. Please book one seat for me, please.
Success. Your reference number is PMHZ3TJO.
I am also looking for a hotel with free wifi, but it doesnt need to have free parking. 
Do you have a preferred area or price range?
The area doesn't matter, but I would like it to be an expensive 4 star hotel.
I have 2 options for you. The first is the Huntingdon Marriott Hotel in the west. The other is the University Arms Hotel in the centre. Do you have a preference?
The Huntingdon Marriott Hotel sounds really nice. Could you book us a room there for 2 nights on Tuesday?
How many people will be staying for the booking?
Just one person please
Unfortunately they are booked up for those nights. Would you like to try another night or the University Arms Hotel instead?
Try booking the room for just one night, please.
That worked. I have you booked on Tuesday for 1 night. Your reference number is 7IX0V6NU. Can I help you with anything else?
Thank you but that's all.
Let us know if you need anything else? Good bye.
