I need help finding a train.  Can you do that?
Of course. Where are you traveling to?
I would like to leave Liverpool street on Tuesday and arrive in Cambridge.
We have 10 different trains on that day. Do you prefer a particular time?
I would like to arrive in Cambridge by 08:45. 
TR6939 is your best option. It will leave at 05:39 and arrive at 07:07. Would you like to book passage on that train?
Yes, I'll need 7 tickets.
Okay, do you need a reference number?
yes please tyhat you for all your help
OK, you have 7 tickets reserved on TR6939. Total due at the station will be 116.2GBP. Your reference number is OK7WYTNQ.
I also need a place to stay.  2 star is my preference. 
okay, what area and price range?
In the west part of town. The price doesn't matter.
I don't have any 2 star hotels in that area. Would you like a different area or a higher rated hotel?
do  you have one with  a star of 4?
I do. We have three options. Two that are cheap and one that's expensive. Do you have a preference?
Try either one of the cheap ones, I need one that can hold my group of 7 for 5 nights on tuesday.
the cambridge belfry was the best match for a large group so I booked you there, the reference number is X33MYBK5 , may I assist with anything else?
No, thank you. That will be all.
Have a great time.
Thank you for your help.
You're welcome, and have a great day.
