Hi, I could use help with my planning.  I am trying to find a place to stay.
Ok, to help us find the right place for you lets talk about what you would like. Do you have a price range you prefer? Or an area of town?
I would like it to be in the south and have a rating of 3 stars.
We have a moderately priced guesthouse and an expensive hotel that match your requirements.
Does either offer free parking?
They both offer free parking and internet.
Okay can you please book it for 7 people for 4 nights starting on Tuesday?
Which one? The guesthouse or the hotel?
The hotel, please.
Reference number is : BS0ODSGJ. Is there anything else?
Yes, I also need a train from stevenage to cambridge. I want to leave after 10:15 on tuesday.
I have train TR0517 that leaves at 11:54. Would that be something that would work for you? 
That's perfect. Could I get the train ID and travel time?
The travel time is 49 minutes.
Great, that's all I need, thanks so much for your help! Have a great day!
You're very welcome! Thank you! Bye!
