I need  a train that leaves for Ely on Friday.
What time do you need to travel to Ely?
I need to arrive in Ely before 11:30. I would be leaving from Cambridge. 
There are 3 trains that fit that criteria - is there a specific time you'd like to leave?
Yes, I would like to book a train that will arrive in Ely before 11:30.
TR8792 departs Cambridge at 9:50 and arrives in Ely at 10:07. Would you like a ticket on that train?
I also need a place to stay on the north side of town that includes free parking.
We have several guesthouses, one hotel and one lodge that meet that criteria.
Do any of them have 3 stars?
Yes, the Hamilton Lodge has only three stars. It is a guesthouse in the north part of town. Would you like me to book you here?
No, but I do need the address, postcode, and phone number.
Sure, The Hamilton Lodge is located at 156 Chesterton Road, cb41da.  You can call at 01223365664.  Is there anything else I can help with?
That is all I need. Thank you.
TR8792 is the latest departing train on Friday. It departs at 9:50 and arrives in Ely at 10:07. Do you want to depart earlier?
I didn't need a train. I have everything I needed now. Thank You for your help.
No problem. Enjoy your stay in Cambridge!
