Yes, would you be able to help me find a train leaving from Cambridge?
I can definitely help with that. What day would you like to travel? And what is your desired destination?
I want to travel on Saturday from Cambridge to Kings Lynn.
There are 19 different trains on Saturday from Cambridge to Kings Lynn. What time would you like to arrive by?
I would like to leave after 14:30. Could you find me a train for that time?
The first train to leave after 14:30 is TR6982 and leaves at 15:11
OK, could you book me 7 tickets for the TR6982?
Booking was successful, the total fee is 54.88 GBP payable at the station. Is there anything else I can help you with?
I'm looking to stay in a guesthouse while I'm there. I'd like a place that has free parking.
There are a number of guesthouses.  Do you have a price range and an area that you prefer?
No. What is available?
I have 21 places that fit what you want.  Do you have a price preference?
Not at the moment.  Can you recommend any moderately priced guesthouses to accommodate  7 people?
Is there a specific area of town you would like to stay in?
Not particularly. I just need one for 5 nights starting Monday. Whichever you recommend. 
I am very sorry, but I was unable to book a guesthouse, would you be able to check in at a later day, or could you stay for a shorter period?
Can you book it for 3 nights? 
You're booked at the Acorn Guesthouse for 3 nights, 7 people, starting on Monday. Your reference number is WU51A5WI. Can I help with anything else today?
I do not need anymore help. Thank you for your help. 
Thank you for allowing me to assist you.  Enjoy your stay!  Let us know if there's anything we can assist you with in the future!
