Hello, I am going to be visiting Cambridge soon and I am interested in what attractions are in the centre.
I can help you with that!  There are many different types, and many people love the architecture attractions.  Would you like to hear more about one of those?
Yes. Tell me more.
Little saint mary's church is a great place to visit. It is located on little saint mary's lane in the centre of town and its free to get it.
Ok, thanks! What about a train to get me to Cambridge? 
Where will you be departing from?
I will be leaving from Stansted Airport. 
What time would you like to leave or arrive by?
The train needs to leave after 16:45 on Tuesday please. 
Tr2101 is leaving at 17:24, would you like me to book tickets and if so how many people?
Thank you for the train ID, what is the travel time for that train?
The travel time is 28 minutes. May I be of further assistance? 
Nope! Thanks for everything. That's all I needed. 
If we can be of further assistance, please reach out to us again. Good-bye.
