Hello, I am looking for a train to Cambridge and need to arrive by 15:00.
Where are you heading in from? And what day?
I'm leaving london liverpool street on sunday
TR9835 arrives at 13:07, would that work for you?
Yes, and I need to book this for four people.
I was able to book 4 tickets your reference number is 9EBGT2IQ. The price for the tickets is 53.12 GBP, is there anything else I can help with? 
I also need to find a moderate priced place to stay with a 3 star rating.
There are four guesthouses that are moderately priced and have three stars. What area would you like to stay?
I don't have a preference. Can you make a  suggestion?
Hamilton Lodge is nice. Would you like me to book it?
Sure!  I need to get rooms for the same group as riding the train.
How many nights do you plan to stay?
I would be there for 5 nights.
Okay. Your booking was successful. Your reference number is KGCK4JK6. Can I help you with anything else today?
That is everything thank you.
You're very welcome! Have a great day!
Thank you. I appreciate your help.
You're very welcome!
