U: i want to go to a park

S: Sure, there are a few.  What part of town do you prefer?

U: anywhere is fine. May I get a postcode ?

S: There are 5 different parks. Postcodes are CB21JF, CB18DW, CB46AZ, CB22AD, and CB223AE.

U: I'm also looking for a hotel to stay in. I need to make sure it's a hotel and not a guesthouse, with a star of 4.

S: I have three 4 star hotels. what are or price range do you prefer?

U: The price doesn't matter.  I do want it to be in the north area of town though.

S: I'm sorry, I don't have any 4 star hotels in the north. Would another area be ok, or should I check other star rating options?

U: Are there any 4 star guesthouses in the north available?

S: No, I'm afraid there aren't.

U: Could you look for something that isn't a guesthouse then?

S: There are no hotels that meet your requirements.

U: I guess I will take the guest house.

S: Okay, Do I need to book that for you?

U: Yes, please, for 6 people, for 4 nights, starting Wednesday.

S: I'm sorry, but I'm afraid we'll need to try different criteria. Would you be willing to change what part of town you stay in, or the star rating you need?

U: But I said I would take the guesthouse.

S: I'm so sorry about that.  You are booked at the Acorn Guest Lodge.  Reference number is : R68P0A12.

U: Is it in a good location?
S: ACORN GUEST HOUSE's location is extremely safe and comfortable, however most reviews state that it's a bit far from any of the local nightlife.
