Task-oriented dialogue about: hotel

Can you locate me a hotel on the east side with free parking. Please provide me with the reference number.
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?
I would like one with four star. I don't care about the price.
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?
Let's try the Allenbell. Could you make a reservation for 1 person, for 5 nights starting Wednesday?
No problem. Your reference number is GWQNWQXD . Anything else?
No, that's all I needed today. Thank you for your assistance!
Enjoy your stay! Goodbye!
