I would like to book a hotel room for two.
Okay, is it possible you meant to say you needed to find a train? I can help you with that. 
Yes, sorry.  I need to leave Stansted airport on Tuesday.
And what is your destination?
Cambridge. Please give me departure time and travel time.
Would leaving at 5:24 and arriving at 5:52 work?
It most certainly would, thank you.  I am not ready to book, can you just give me the travel time for that trip?
The travel time is 28 minutes. Is there anything else?
No, that's all, thanks.
You're welcome. Have a great day!
