I'm looking for a place to stay, in the north.
What price range would you like? Would you need free internet or parking?
I'd like a guesthouse in the north, I don't care about the parking. Price is no issue.
The acorn guest house is in the north in the moderate price range and has a 4 star rating. Would you like to book a room?
Yes, I would like to book it for 5 people for 5 nights starting on Friday. Can you give me a reference number?
Sure!  The reservation is set.  Your reference number is EOPOKFF6.  Is there anything else I can help you with today?
I also need a train.
Where are you leaving from and going to?
 I'm going from Cambridge to Birmingham New Street on Wednesday. 
There are 19 trains on Wednesday. When would you like to depart?
at 5:15 would be a good time thank you 
There are no trains leaving at 5:15. The TR0115 leaves at 5:01. Would you like to book it?
Woah now, that's way too early. I actually don't need to get in until 19:00. 
I hear ya'. How about TR1038? It leaves Cambridge at 16:01 and gets into Birmingham New Street at 18:44. Would that work for you?
What's the price per ticket and travel time for that one?
75.10 pounds and it is a 163 minute trip.  Is there anything else, that I can assist with?
Have a nice day.
You too. Have a great trip.
