U: I want a hotel with free parking in the center of town.

S: Sure, I can help you with that.  Do you have a price preference?

U: Something moderate would be preferred.

S: I am sorry but there is nothing in the moderate price range.  Would you like another price range?

U: What about a moderate hotel located in the North?

S: I have found 9 hotels in north. Do you have any other preferences so we can narrow them down?

U: No other preferences.  Can you pick one and book it for 6 people for 3 nights starting Friday

S: I was able to book your party of 6 into Acorn Guest House, reference 1IJ5VMO1. Is there anything more today?

U: Is Acorn a good value for the money?
S: All of the reviewers thought that the acorn was a good value. Is there any other information you need?
