Can you help me find a train leaving after 18:00 on wednesday?
Can you please give me your departure and destination, please?
I want to leave after 18:00 to Broxbourne from Cambridge.
I have one departing at 19:01. Would you like me to book a ticket?
How much is the price per ticket?
17.90 pounds. Would you like me to book it?
I'm also looking for a place to stay in the moderate price range.
Is there a specific area you would like to stay in? 
I would like a hotel in the north side with four stars, please.
There are 7! Do you need internet and parking?
No but it needs to be a guesthouse.
I have five places. Shall I book you one?
Please, for 7 people, 4 nights.  The same day as my train.  What was the travel time on that train again?
I have booked you at Acorn Guest House. Your reference number is MMSZTKRS. Your train trip is 60 minutes long, but you've not booked. Would you like to do that now?
Thank you, that is all the information I needed.
You're welcome, have a great day!
