I am planning a trip to Cambridge and need to find a place to stay.
Not a problem. We have 33 places to choose from. Do you have any preferences?
I need someplace cheap near the center of town. Free wifi and free parking are a must.
There are two places that fit your criteria. Alexander Bed and Breakfast and El Shaddai. Which are you interested in?
Let's book El Shaddai for 4 people for 2 nights starting Sunday. Can you please send me the reference number?
Your reference number is QLYJQKTY .
I will also need a train departing from Cambridge.
I will need more information to be able to help you find the correct train, where are you headed?
I need a train on Tuesday from Cambridge to London Kings Cross that arrives by 8:30.
I have two trains. One arrives by 5:51 and 7:51, shall I book one for you?
No, that's OK. Can I get the latter train's ID, departure time, and how long the trip is?
The TrainID is TR3343. It departs Cambridge at 7:00 and arrives at London Kings Cross at 7:51. The trip duration is 51 minutes.
Great, thanks. I think that's all I need. Thank you for all of your help.
You are welcome. Have a great trip!
