I need to find a train leaving Cambridge and going to Ely. Can you help?
I can help! There are many options
I need to leave on Friday and arrive by 21:45. 
There is the TR6053 that arrives by 20:07. Do you want me to book it? 
What's the travel time on that one?
You can book TR6053 since it is only a 17 minute trip. Thank you
What time does that train leave Cambridge? I also need a place to stay in Ely, with free parking and free wifi?
The train leaves ely at 19:50. Would you prefer a guesthouse or hotel?
Really makes no difference to me as long as its on the North side of town
I have about 11 different places so far. Do you have a certain price range in mind? That may help narrow it down some. 
I will take any suggestions you have. 
The hamilton lodge is moderately priced and has 3 stars. Would you like to make reservations?
Can you confirm if the hamilton lodge has both free parking and free wifi?
Yes, the hamilton lodge has free parking and wifi. Would you like me to book?
No, not today. I just needed information.
No problem, anything else besides the hotel and train today?
no that is all thanks
You are welcome. It was a pleasure serving you from Cambridge TownInfo centre. Goodbye.
