I need to get to Cambridge on Sunday. Can you find me a train from Kings Lynn please?
We have several different time slots for Sundays train to Kings Lynn. What time is good for you?
I need to leave after 15:00.
The first train to Cambridge from Kings Lynn departing after 15:00 is the TR2965, leaving at 15:11. Would you like to reserve a seat on this train?
Yes.  Please book that for 3 people. 
I booked the train. Your reference is HFQYOUMG. Do you need anything else? 
I am also looking for a hotel on the north side of town with a 1 star rating
What is your preference on price?
I do not have a preference on price, but it must include free parking.
I'm sorry, we don't have any hotels fitting your criteria. Would you like to search for something different?
If there is no such hotel, how about one that has a star of 4
I'm sorry I do not have any 4 star hotels in the north part of town with free parking. Is there anything else I can do for you today?
Huh. That's odd. I was told there was a good one. 
On the north side there are 2 moderate priced hotels both have free parking and internet. They are both 2 stars. Would you be interested in one of these?
I really would prefer a 4 star hotel. Can you please look again on the north side?
I looked again, and there's nothing meeting your criteria. We have several 4 star guesthouses in the north with parking, would that work?
Sure, I'll need it for the same group of people for 3 nights. 
Would you like me to recommend a 4-star guest house is the north?
Would you like me to book it for you ?
I would recommend the acorn house.
Ok, can you book for same group of people 3 nights starting on same day?
Booking was successful. Reference number is : VTJW67PC. Acorn guest house starting Sunday for 3 people and 3 nights. Is there anything else I can assist you with?
You have helped me with everything I need today.  Thank you! That will be all.
Have a great time.
