Hi, I'm looking to take a train on Tuesday and heading to Cambridge. 
Where are you leaving from?
I will be leaving from Ely.
ok, what time do you want to depart?
Well I want to arrive by 16:15.
You have quite a few options. Would you rather leave early in the morning because trains run every two hours from 05:35 ?
I could leave in the morning.
How many tickets please?
I don't need tickets just the information for the train. I need the train ID please. 
The train ID is TR8685.
I also need a place to stay with free wifi. 
Do you have a preference? Hotel rating, location, parking, or internet availability?
I'd like a guesthouse in the expensive price range with free wifi, please.
We have no guesthouses in the expensive price range. Can I find something else for you?
Any guesthouse in the cheap range?
Yes! How about Allenbell?
I would like to book 5 people for 5 nights the same day.
Your booking was successful. Reference number is 6GDIBPKO. How else can I help? 
That's all I need. Thank you so much.
