Yes I'd like to find a hotel with free parking and 5 star rating.
I'm sorry I can't located anything with that criteria.
Can you try it in a different area please?
I apologize but I don't recall you mentioning an area you preferred. Can you tell me what area and I will search again for you? 
I don't have a preference, but I guess we could stay in a four star hotel with free parking if we absolutely had to. 
We have plenty of those! Surprisingly, the 4-star places we have range in price from cheap to expensive. Do you have a preference?
I'm actually looking for a 5 star place. Any available?
No, I can't find anything with 5 stars, do you want to try something else? 
Sure, let's try a 4 star hotel.
acorn guest house	is found in the  north 154 chesterton road	
I would actually like a 4 star hotel, not a guesthouse.
How about the University Arms Hotel in the centre of town? Does that sound nice? I can book you a room if you'd like.
Is the University Arms a 4 star hotel?
Correct, it is a 4-star hotel in the centre area. Would you like to book it?
Please book it for 8 people starting Monday for 3 nights. 
I'm sorry, I was unable to book the hotel for the time frame that you desire.  Would you like to try another night or a shorter stay?
Ok, can we try 2 nights instead please?
Booking was successful.
