U: Hi, I am looking for a train that will be arriving by 16:00 in Cambridge.

S: What day and from where?

U: I am leaving Friday from Kings Lynn.

S: We have a train departing from Kings Lynn, Friday at 15:11 which will be arriving at 15:58. The price is 9.80 pounds and the total duration of the trip would be 47 min. Would you like me to book this for you?

U: Thank you for all the information. I would like to book this.

S: Consider it done. It has been booked. Anything else?

U: Yes, can you also help me find a hotel that has free parking and is expensive?

S: Sure! Let's narrow it down a bit. Any preferences on location or star rating?

U: I would like a 4 star hotel.  Location isn't important, just quality hotel.

S: Sure thing! There are 21 four star hotels. Do you have any other needs, like internet, parking, or price range or style?

U: I would like it to have free parking and internet.

S: The Huntingdon Marriott and the University Arms are both expensive 4-star hotels with free internet and parking. Is either of these of interest to you?

U: The University Arms sounds good. I'd like to book 4 nights for 1 person, beginning on Friday. And I'll need the reference number, please.

S: You booking was successful. Your reference number is XWZQ8GBA. What else can I help you with?

U: Are the bathrooms spotless here?
S: The University Arms Hotel has a couple of comments about how clean their bathrooms are, but they also have another comment that says their bathroom wasn't very clean when they first arrived.
