user: I want a train that goes to stansted airport and leaves from cambridge.

assistant: There are many that leave cambridge and go to stansted airport; what day would you like to leave and what time?

user: I need the train to leave after 09:15 on Saturday.

assistant: I have train TR2755 that will leave at 09:40 and put you at the airport by 10:08. Would that work for you? If not, I have later trains.

user: That train works well.

assistant: Would you like me to book this train for you?

user: Yes please. Get me 8 tickets for my party as well as a reference number.

assistant: Your reference number is UKOTND0A . Would you like anything else today?

user: I also need a hotel that has free parking. I don't need internet or anything like that.

assistant: I have 29 places to stay with free parking. Is there a price range you'd like to stay in?

user: Are any of the 29 places, guest houses? I would actually prefer a hotel rather than a guest house.

assistant: There are 8 hotels that match that description. Did you have a price range or area in mind?
