I would like to find a moderately priced hotel to stay in that includes free parking. Can you help me?
There are many options in this price range. 
Are any of the options guesthouses with 4 stars?
There are 9 in the area. I recommend the Warkworth house.
Can you book that one for 4 nights starting on Wednesday?
I can do that, but first, can you confirm how many guests will be staying?
Yes there will be one guest. I will need the hotel reference number. I also need a train that arrives by 20:30 and leaves on sunday 
I have made those reservations. Your reference number is 5JGRH1VH.

What time would you like to leave?
