U: Hi, I need a train that departs from cambridge.  I need to leave after 15:00.

S: There are many trains that depart Cambridge at that time, what day do you need the train and where are you going?

U: i am going to peterborough on tuesday.

S: I have 18 trains available.  What time would you like to arrive?

U: I would like to arrive by 18:00 if possible.

S: I have train TR6357 that leaves at 17:06 and arrives in Peterborough at 17:56. Would that work for you?

U: Thanks.  I also need a place to stay.  Can you find a guesthouse with free parking?

S: Would you like me to book the train? There are 21 guesthouses that offer free parking do you have an area you'd like to stay or price range?

U: I'll deal with the train, thank you.  I want a fancy expensive guesthouse, does that narrow it down any?

S: I have no expensive guesthouses in Cambridge. Is there another price range you would be willing to accommodate?

U: Please try for something in the cheap price range.

S: There are many guest houses that fit this criteria, do you wish to stay in a certain area?

U: I don't know the area. Can you suggest something for me?

S: The Alexander Bed and Breakfast is lovely.  Would you like me to reserve rooms for you?

U: Are there good breakfast options at the Alexander Bed and Breakfast?
