U: Hi there. Can you help me find a train leaving on Friday?

S: Please tell me what town are you departing from and what is your destination?

U: On Friday, I would like to arrive in Cambridge by 16:45.

S: There are over 100 trains available, could you please provide a departure location?

U: I would like to leave from london kings cross.

S: ok I have one leaving by 05:17, TR5219, would that be fine?

U: Do you have one that arrives a little closer to 16:45. I don't want to get in too early.

S: TR8842 will get you there at 16:08.  May I book it for you?

U: Yes, I need it for 8 people.  I'm also looking for a guesthouse type hotel with free parking in the moderate range.

S: Do you have a preference for the number of stars or the area?

U: May I have a reference number for that train, please?

S: Your reference number is RRNTTR7Z. We also have quite a few guesthouses, do you have an area you'd like?

U: For the guesthouse, do you have one in the moderate price range that includes free parking?

S: There are 12 options for moderately priced guesthouses, any area preference?

U: The area doesn't matter. I just need one with rooms available for 3 nights starting on Friday.

S: For how many people?

U: I need it to be for 2 people.

S: The Acorn Guest House on 154 Chesterton Road should be sufficient, shall I reserve a room for you now?

U: Do you know if the showers in the rooms are high pressure?
S: Guests have said that the water pressure is not very good and is hard to get use to.  Others have said that it is nothing to write home about.
