Task-oriented dialogue about: hotel

I am looking for a hotel with a 3 star rating and free parking
There are 2 hotels with a 3 star rating and free parking. Would you like to stay in the centre or south?
Either is fine. I'd like a guesthouse.
Sorry, I was mistaken. There are 3 guesthouses matching your request. One each in the south, north, and west. Would you like to book one?
Yes please. Which is the cheapest?
I can only tell you they are all in the moderate price range. Do you have any other preferences?
No. I would like to make a reservation for Wednesday for 3 nights and 8 people. I will also require a reference number.
I was unable to book your stay at any of the three hotels. Would you like to change the length of your stay or change the day?
Can you please try a 2 day stay.
Booking was successful for the bridge guest house. Your Reference number is : LBEOV690 .
Thank you. Have a nice day.
