Yes thank you.  I'd like to stay in Cambridge.  We're looking for a hotel with free parking and free wifi.
There are quite a few like that. If you're open to guesthouses , Limehouse in the north of town is nice. Or were there other features you were looking for?
Do you have one in the east with an expensive price range? 
Yes, on, Holiday inn Exlpress, Cambridge, shall I book it?
yes, please. For 6 people for 3 nights starting on friday.
Your booking was successful! Your reference number is JBBPQWA1. Is there anything I else I can help you with today?
I need information on a train as well.  It should leave after 18:45.  
Could you please clarify your departure location and arrival destination?
Coming to Cambridge from broxbourne on Friday.
I have train TR5056 that departs at 19:32 and arrives by 20:32. Would that be something that would work for you? 
Yes, that would work for me.I will just need the price, train id and travel time.
TR5056 costs 17.90 pounds and the duration is 60 minutes.
Okay thank you that's all I needed.
It was a pleasure serving you. I do so hope that your stay in Cambridge is pleasant. Goodbye!
