Can you help me find a train leaving after 12:15 on friday?
Sure, what's the departure and destination.
from broxbourne to cambridge
The TR3158 meets your description. Would you like to make a booking?
What is the arrival time? I'll also need the travel time and train ID.
The arrival time is 13:32. The train ID is TR3158. And the travel time for this route is 60 minutes. Anything else I can do for you?
I also need to find a hotel with free parking and wifi. 
There are 8 hotels available with internet and parking. What price range and area of the city are you interested in?  
I want to to have a 4 star rating & be a guesthouse. It can be in any area of the town.
There are 16 options available.  Can I narrow it down for you by price range?
The price doesn't matter. Is there one that you would recommend?
I would recommend the Allenbell which is in the center and cheap. Would you like to make a reservation there?
Yes please, for 3 people.  We'll need 3 nights starting Friday.  Can you please give me the reference number once it's booked?
Your room has been booked. Reference number is 77BQDD6I.
Great, you have been very helpful today.  Thanks. That is all I need.  Bye.
It's my pleasure.  Have a good day.
