I need to find a place to stay.  It needs to include wifi and I would like a 3 star. 
Ok, I have 2 hotels and 3 guest houses matching that request. What part of town are you wanting to stay in?
Are any of them moderately priced and have free parking?
Yes there are 3 different options. Would you like to stay in the north, west, or south?
You may decide which area would be good, just let me know which area you pick. 
I recommend Hobsons House in the west. Would you like to book a room?
No but I also would like to get a train leaving from peterborough.
OK, what day and time do you need to travel?
I would like a train on monday and need to arrive by 13:30
I have train TR7895 that will get you into Cambridge at 13:09. Would that work for you? 
That sounds perfect. I'll book it later. That's all I need. Thanks for everything.
You're very welcome! Take care!
