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?
