I am looking for an expensive 4 star hotel.
I am showing five hotels that fit your criteria. They all offer internet and parking. Is there a specific area you want to be in?
No, but the hotel should be in the type of guesthouse.
I'm sorry, there aren't any expensive guesthouses with 4 stars, but there are 18 moderately priced 4-star guesthouses. Would that be okay?
Is there one available in the cheap price range?
I have 7 cheap 4 star guesthouses,can I recommend autumn house?
yes that sounds nice, can you check for booking for 5 people and 3 nights starting from monday?
Yes, I will book at autumn house for 3 night for 5 people starting Monday.
Can I get that reference number please?
Unfortunately the booking was unsuccessful.  Would you like me to look at another hotel?
please recommend another hotel in that same price range.  
Alexander bed and breakfast is is the centre location. Also a 4 star cheap guest house. How does that sound to you?
Book it please. 
I have made reservations starting monday for 3 nights and 5 people the reference number is JCCYU8ZS. Is there anything else I can help you with?
No thank you. Good bye.
Goodbye. Have a great day!
