U: Can you locate me a hotel on the east side with free parking. Please provide me with the reference number.

S: We have listings for 5 hotels and 1 guesthouse on the east side with free parking. Do you have a price range in mind so we can narrow it down?

U: I would like one with four star. I don't care about the price.

S: I have 5 guesthouses that meet that star requirement. The Allenbell, Autumn House, and Leverton House are all cheap. Carolina B&B and Warkworth House are moderate. Do you have a preference?

U: Let's try the Allenbell. Could you make a reservation for 1 person, for 5 nights starting Wednesday?

S: No problem.  Your reference number is GWQNWQXD.  Anything else?

U: Can you tell me whether the Allenbell offers nice rooms with great views?
S: The Allenbell offers scenic views from its balconies that many guests gush over. Do you want to know anything else?
