U: I'm looking for a 3 star lodging with free parking.

S: I have 5 hotels that meet that criteria. What area of the city would you like to stay in?

U: I think I would like it near the centre. Does it have free parking? I would like the price range to be cheap but at least a 3 star hotel.

S: I have a listing for gonville hotel but it is expensive, I have looked in other areas and the cheapest are moderate.

U: What hotels are available in the moderate price range?

S: I'm sorry there are no hotel that are moderate in the Centre of the city. Would you like a different part of town?

U: No. Are there any guest houses in that range?

S: I'm afraid not. Perhaps a different star rating?

U: I'm sorry. Could you just find me one with free parking, a 3 star, moderate. I don't care where it is located.

S: There are 3 including bridge guest house.

U: OK, can you book me for 1 person for 5 nights starting on sunday?

S: Booking was unsuccessful. Want to find another hotel?

U: Please book a different hotel in the same price range.

S: Do you care whether it is in the same area or not?

U: No, the area is not important. Just the same price range, if you can find anything.

S: I have you booked at Hamilton Lodge. The reference number is TGSVA9OC. Is there anything else I can help you with?

U: How are the mattresses at this hotel?
S: Aside from a couple rooms that requires a new mattress, the Hamilton Lodge provides extremely comfortable beds for its guests.
