Sure, I can help you with that.  When were you wanting to depart? 
I need to leave cambridge after 14:15 on saturday
How about the TR3735, that leaves Cambridge for Birmingham New Street on Saturday at 15:01, would that work for you?
That works great! Can you get us a reservation for 3 people?
I can get that completed for you.  Did you need a reference number?
Yes please.  Also, I am interested in some places to go in town.
Is there a particular type of attraction you're interested in?
I would really like it to be in the centre of town and some type of entertainment.
