U: I need information for a train from cambridge to norwich.

S: There are several trains departing from Cambridge arriving in Norwich at a price of 17.60 pounds.  What day are you looking to travel?

U: I am looking to travel on Sunday, and leave after 21:30

S: I have train TR7767 leaving at 21:36 and arriving by 22:55. Would that be something that would work for you?

U: Yes please book for 1 person and send the reference number.

S: Okay, I've done that for you. Your reference number is 0TDRHZKN.

U: Thank you. I also need a place to stay. Can you find me a three star guesthouse?

S: Sure, what area of town are you interested in?

U: In the centre I guess.  I do need free parking.

S: I'm sorry, there aren't any 3 star guesthouses in the centre, would you like to try another level?

U: No, can you check for a 3 star guesthouse in the west?

S: Yes, there is the hobsons house. Shall I go ahead and book that for you?

U: Not yet, could you first let me know whether Hobsons House offers good views from the rooms?
S: Yes there are good views at Hobsons House. Former guests describe the views as amazing and breathtaking.
