U: Hi, I'd like to book a train leaving from Birmingham New Street and arriving in Cambridge.

S: When will you be traveling?

U: I will be traveling on Sunday, and need to arrive by 10:00.

S: The train that will arrive closest to your preferred time is TR9637. It arrives in Cambridge at 09:23. Does that work for you?

U: Yes that works great can I have the departure time?

S: It leaves at 06:40. Would you like me to book it for you?

U: Yes and I need a place to stay in the east and a 4 star

S: I want to confirm you want to book one seat on the train, is this correct?

U: Actually, I'll book it myself, thanks, but I would like to book a guesthouse as well.

S: I have 24 guesthouse. Is there a certain side of town or price range you have in mind?

U: I would like a moderately priced guesthouse please.

S: There are three 4-star guesthouses in the east in your price-range. Will you need free parking?

U: No, that's not really necessary. What are my 3 choices for guesthouses?

S: I have the A and B Guest House, the Carolina Bed and Breakfast, and lastly the Warkworth House. The only difference between them is the A&B has no free parking.

U: Can you tell me which of the three have the most comfortable beds?
S: The A and B Guest House and the Warkworth House both get high ratings for the bed comfort. The Carolina B&B has mixed ratings. Would you like to know more about any of the places?
