Hi, I need a train Wednesday that will arrive by 19:45.
There are many trains that meet that requirement. Where are you headed?
I'm headed from Cambridge to Broxbourne.
When would you like to depart? You can select any hour between 05:01 and 18:01.
I don't care about that, you choose for me. Can you book me tickets?
Train TR3279 departs cambridge at 9:01 and arrives in Broxbourne at 10:01. Would you like me to book you a ticket?
Yes, I need three tickets and a reference number, and I would also need a guesthouse with free parking.
There are 21 guesthouses of that type in Cambridge. Is there an area or price range you would prefer?
How about a moderately priced 3 star guesthouse?
There are 3 different guesthouses that fit that, one in the north, one in the south, and one in the west. Do any of these areas work for you?
Yes I'll take the one in the south, thanks for your help.
That's the Bridge Guest House. Would you like me to book a room for you?
No, that's okay. Could you get me the reference number for my train tickets, though?
Your booking was successful. the total fee is 53.7 GBP and your reference number is ZLBJ2U2O .
Great, thank you! That's all I needed.
Thank you and enjoy your visit.
