Hello, can you give me some information on a train?
I absolutely can. Where are you looking to go?
I plan to go to Cambridge and will be departing from norwich on Saturday and plan to ride a train that should arrive cambridge by 16:00.
Okay, there are several departure times that fit what you're looking for. The earliest is 5:16. Would you like me to book that for you?
Can you give me the travel time, departure time and train id for the one arriving closest to 16:00 please?
Train id is TR2602, travel time is 79 minutes and the price is 14.08 pounds. Is there anything else you need?
Yes, I need a 4 star hotel in the expensive price range.
We have huntingdon marriott hotel in the west and university arms hotel in the centre, any preference?
It needs to have free parking.
They both have free parking. I'd recommend the University Arms Hotel in the centre. Can I book this for you?
I'm sorry, I actually need a guesthouse. 
Unfortunately, I don't have any matches in my system. Is there something else I can look for? 
How about one in the cheap price range?
There are several guesthouses in the cheap range all over town.  What area do you prefer?
