I am planning a trip in Cambridge
I can help you with that. Are you wanting to come in by train?
I'm actually just looking for places to go in the centre. 
Are you looking for a specific type of attraction?
I believe I'd like something in the entertainment area. Is there anything like that?
There are no options in the centre. Would you like to try another area?
Is there anything interesting going on near the college?
I don't have information on events only attractions.  Are you interested in visiting a college?
Yes please. I need the phone number of a college that you recommend. 
I recommend Clare Hall in the west. Their phone number is 01223332360. Anything else I can help with? 
I also need train tickets.
what is your destination and what time would you like to arrive?
I would like to arrive by 17:15.
What day will you travel?
I will be traveling on Thursday. 
Can you tell me your departure and destination cities please? 
Oh, silly me! I guess that information would help, wouldn't it? I need to depart from peterborough and arrive in cambridge, please.
Okay. The TR2526 would meet your criteria. Would you like to book tickets? If so, how many tickets would you like?
What is the total travel time for train TR4526? 
the travel time is 50 minutes
That is all I need, thank you, goodbye!
No problem. Have a great day.
