Hi. I need to book a guesthouse that has free parking, can you help me?
There are 21 guesthouses which offer free parking. Which area do you prefer to stay in?
I am open to any area, but the hotel should definitely have only 1 star.
I was unable to find a 1 star guesthouse with free parking. Would you like to up the stars?
How about 4 stars?
I found quite a few that meet that criteria. How about the archway house?
That is fine. Can I have the phone number and the area that the guesthouse is in?
How about the Archway House which is a guesthouse in the north and their phone number is 01223575314.  I can book it for you if you would like.
That's OK, I'll do it later. Can you tell me if there are any trains departing Cambridge on Tuesday?
Yes there are many trains leaving on Tuesday from Cambridge. What is your destination and the time you would like to arrive?
It should leave after 9:15 and go to Norwich.
The first available train after your preferred time is TR9942 with a departure time of 09:36 and an arrival time of 10:55. Would you like a ticket for this one?
Not right now but can I get the travel time on that?
It's a 79 minute trip, and the fare is 17.60 pounds. Is there anything else I can help you with?
Thank you, that is all the information I need currently. 
You're welcome. Enjoy your day.
