Sure, we have lots of places to go. What type of attraction are you interested in?

Sounds great! Can I get their address and postcode?

I also need a train going to broxbourne I need to leave after 13:00. 
I have several trains going to Boxbourne. What day do you want to leave? Where are you leaving from?
I want to leave on Thursday from Cambridge. 
I have train TR9033 that leaves at 14:01 and arrives in Broxbourne at 15:01. Would that work for you? 
That is all the information I need. Thank you.
Can I get you information on anything else?
No, you have been extremely helpful.  Thanks for everything.  Bye.
You're welcome! Have a great day!
