I am looking for train from London Kings Cross and should leave after 21:30.
We have several trains available. Is there a particularly day you wish to leave on?
I would be leaving on Tuesday going to Cambridge. 
I have one train available that meets what you need. Train TR2471 leaves at 23:17 and arrives on 24:08. Would you like me to book you a ticket for this train?
Yes, please. Can I have the Train ID and total travel time, as well?
Sure. The train ID is TR2471 and the duration is 51 minutes.
Thanks. Can you also help with a guesthouse to stay out? I prefer in the east. 
There are six.  Would you like one moderately priced or cheap?
Doesn't matter, do any have a 4 star rating?
Yes I have many 4 star guesthouses matching your criteria. Do you have a preference for free parking and/or internet amenities?
Sure free parking is fine, let me know if they do or don't. Please also give me a phone number, internet doesn't matter. 
The Carolina Bed and Breakfast has free parking and their phone number is 01223247015, do you want me to book a reservation for you?
No. I don't need a reservation now. Thank you very much for all your help.
Terrific, is there anything else I can help you with today? 
Nope, that'll do it, thanks for your time!
You're welcome. Thanks for contacting the Cambridge TownInfo centre and have a great day.
