I need some help locating a train for Saturday, heading to London King's Cross.
Where will you be departing from, and what time would you like to travel?
I'll be departing from Cambridge and would like to leave at 12:15. 
There isn't a train that leaves at 12:15. The closest one leaves at 13:00 and arrives in London Kings Cross at 13:51. Shall I book it for you?
That would be perfect. Book it for 5 people please and send me the reference number.
Okay, the booking was successful, the total fee is 94.4 GBP payable at the station .
Your reference number is : AJTE5TLW.  Is there anything else I can do for you?
I also need a cheap hotel.
What area would you like to stay in?
I would like to stay in the north please.
There are two guesthouses fulfilling your requirements. Do you prefer city centre north b and b with zero stars or worth house with 4 stars?
Um, I would prefer a hotel rather than a guesthouse. How about the moderate price range?
We have two hotels that meet your criteria. I'd recommend the Ashley Hotel. Would you like to make a booking?
Yes I would, for 5 people please for 2 nights starting on Thursday. 
Booking was successful. Reference number is : RF3EBI6I. Anything else I can help with? 
That is all. Thanks so much!
thank you for using this service good bye
