Hello, I am looking for accommodations with free wifi. 
I can definitely help with that. I have many options. In order to narrow it down, do you have a preference between a hotel or guesthouse? 
Either one, but I insist on 4-star quality.
How about Arbury Lodge guesthouse?  It is in north, is moderately price with free wifi and has 4 stars.
What's the postcode and address for that?
The address is 82 arbury road and the postcode is cb42je
Am I able to park for free there?
Yes, they offer both free wifi and free parking. Do you need me to assist you in making a reservation?
No, thanks. I also need a train on Sunday out of Cambridge. 
There are many. What time would you like to leave and what's your destination?
I want to leave for Peterborough after 18:30. 
I've booked you a ride on train TR8255, your reference number is E1SGGIUC, the ticket will cost 13.20 pounds. Is there anything else I could help you with?
I just need the arrival and travel times for that train, thanks.
TR8255 departs at 18:34 and arrives at 19:24.  Hope that helps!  Any other questions?
You have been a great help.  Thank you very much!  Goodbye!
You are welcome! Enjoy your stay!
