U: Yes, I was wondering if you could assist me in finding a train for Monday.

S: There are 2828 trains available Monday. Where are you traveling to?

U: I am traveling to London Liverpool Street from Cambridge.

S: There are 10 trains that meet your criteria. Do you have a preferred time that you would like to arrive by?

U: Yes, I need to leave after 17:30, please. I don't need tickets right now, I'll just need the price, travel time, and train ID.

S: Of course! The best option is the TR7092 leaving at 17:59 with a duration of 88 minutes. The price is 16.60 pounds. How else may I assist you?

U: I'd like to find somewhere to stay with free parking; I'm planning to rent a car during my stay.

S: I have found 29 hotels that fit your criteria for parking. What price range are you looking for?

U: I would like to stay in a guesthouse that is in the south.

S: There are three guesthouses in the south with free parking in the moderate and cheap price ranges. Do you have a star or price range preference?

U: Not really. Would you see if the highest rated, least expensive guesthouse has rooms for 5 nights for 6 people, beginning Wednesday?

S: I was able to book Rosa's Bed and Breakfast for you for 5 nights for 6 people starting on Wednesday. The reference number is RTITW2L5.

U: Are the breakfast options as great?
S: A free English breakfast is served with plentiful and tasty options such as bacon and eggs available. Do you have any other questions?
