I need to take a train on Tuesday. I want to visit somewhere I haven't been before.
That sounds like fun! Will you be departing from Cambridge or somewhere else?
I need to depart cambridge and head to the stansted airport and arrive by 12:15
There are several options for you, leaving hourly. The TR7293 leaves at 11:40 and arrives at 12:08. Would you like me to book that for you, or perhaps an earlier one?
That sounds great.  Can you book 4 seats for me?
Sure. I have done so and your confirmation number is VOONS2E2.
I am also interested in places to go in town centre.  Can you offer me some ideas?
There are numerous options available. Were you looking for free attractions? There are some great free museums. 
Sure, a museum sounds good, which one would you recommend?
I just love the Museum of Archaeology and Anthropology. They're in the city centre and have no entrance fee.
That sounds perfect. I will check it out, thanks.
You're very welcome!  Is there anything else I can help you with today?
That is all, goodbye.
Goodbye. Enjoy your trip.
