i don't have a preference. I would like a room with a 0 star and free parking
Okay there is city centre north b and b would you like me to book it for you?
I prefer one in the east. How about a 4 star hotel with free parking there instead?
There are no 4 star hotels in the east section of town that offers free parking. Would you like to search for a guesthouse?
Yes that is fine I need the price range as well. 
I have several options in the cheap or moderate price range with parking and wifi. How does the leverton house sound?

It's cheap. Would you like me to book a room for you?
Yes please. I also need a train that leaves after 9:00 on sunday

Actually, I apologize no need to book, I was just gathering information.  But I do need information on a train from leicester to cambridge.
