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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

assistant: For how many people?

user: I need it to be for 2 people.

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

user: Yes, please, and I'll need the reference number.

assistant: I was unable to book that room for you. Can we try a shorter stay or a different place perhaps?

user: Sure, please try 2 nights.

assistant: The booking was still unsuccessful. Would you like to try a different day?

user: Could we please try a different hotel that is close to The Acorn Guest House?

assistant: I checked with all 7 guesthouses in the north and none are available for even a one day stay starting Friday. Could we try a different day?

user: Well I guess I'm out of luck, unless there are hotels in adjoining towns I could try.

assistant: Sorry, we only work with places in cambridge.

user: I am so sorry, can we start over with the guesthouse? I do need a moderate, but for 8 people. Still arriving Friday for 3 nights.

assistant: I could not book a room for that number of nights on those days in that area. Perhaps try a different area?

user: Please try 2 nights on Friday and see if that works. For a guesthouse, please.

assistant: Your room is booked at acorn guest house for 8 people and 2 nights starting on Friday. Reference number is 3M1I4Q7S . Anything else I can help with?

user: No, that should be all I need. Thanks for your help!

assistant: It was a pleasure being of service. Enjoy your stay in Cambridge and call again if you need any further assistance. Goodbye!
