I'm looking for train tickets, can you help with that?
Yes, Where will you be arrive from and going to?  I also need a date and time.
I want to go to peterborough and depart from cambridge. 
There are many trains going to peterborough from cambridge. What day and time do you want to leave?
I'd like to leave Thursday after 8:30 please.
I have train TR6009 that leaves at 08:34 and will arrive in Peterborough at 09:24. Would that work for you? 
What is the travel time?
The travel time is 50 minutes. 
Are there any 2-star hotels (not guesthouses) in the south that have free parking?
No, I'm sorry there aren't any hotels that meet that criteria. Would you like to try a different area?
Is there anything in the north?
In the north, I have 2 places. The first is the Ashley Hotel and the other is the Lovell Lodge. Did you need me to book you a room? 
Yes please book me a room for 4 people for 2 nights starting from Tuesday.
Booking was successful at ashley hotel	.
