Hi, I need a train from stansted airport that arrives by 14:30. Can you help?
I sure can help with that!  Can you please tell me where you will be traveling to?
Yes I will traveling to Cambridge and want to arrive by 14:30.
TR3659 arrives at 05:52
Could you please tell me the price and travel time of that train?
Sure, price is 10.10 pounds and the travel time is 28 minutes. Can I help you with anything else today?
I also need a place to stay. I need a hotel that is 4 star and of moderate price. 
I have about 11 different options. All are guesthouses. Do you have a preference on area so that we can narrow it down? 
I would like a hotel to the north that is a guesthouse, please.
I show 7 guesthouses that match your criteria.  Might I suggest acorn guesthouse.  They have free parking and internet.  Phone number is 0122353888.
Can you reserve us some rooms? We're a party of 8 and we'd like to stay 3 nights, starting Sunday. Can you check that the train is also on Sunday?
I've successfully booked your rooms, and your reference number is D4TV4G4T.
Thank you,  That was all I needed
Have a nice stay in Cambridge!
