Can you help me find a train leaving on thursday going to cambridge?
sure, where are you departing from?
Departing from Broxbourne and leaving after 17:00.
TR1828 is leaving at 17:32, would you like to do that?
Yes please. I need reservations for two people.
Booking was successful, the total fee is 35.79 GBP payable at the station. Reference number is : 8BR3OQ5V.  What else can I assist you with today?
Thanks.  I am also looking for an expensive place to stay in the north part of town.
Unfortunately, I don't happen to have any places that are expensive in the north. Can I look for something else for you?
Could you please double check to make sure? if that's really the case then try the center
I'm sorry, but the north does not have anything to meet your needs. There are, however, 2 options that meet your needs in the centre. One 3 and one 4 star.
Can I get more info on the 3 star one?
Sure, Gonville Hotel is a 3 star rating hotel located at Gonville Place.  It offers free parking and free wifi.  Would you like me to reserve a room?
Yes, for 4 nights from Thursday, and 2 people. 
Done! Your reference number is V43NQGH7. Can I help you with anything else?
