Hi there. Can you help me find a train leaving on Friday? Please tell me what town are you departing from and what is your destination? On Friday, I would like to arrive in Cambridge by 16:45. There are over 100 trains available, could you please provide a departure location? I would like to leave from london kings cross. ok I have one leaving by 05:17, TR5219, would that be fine? Do you have one that arrives a little closer to 16:45. I don't want to get in too early. TR8842 will get you there at 16:08. May I book it for you? Yes, I need it for 8 people. I'm also looking for a guesthouse type hotel with free parking in the moderate range. Do you have a preference for the number of stars or the area? May I have a reference number for that train, please? Your reference number is RRNTTR7Z . We also have quite a few guesthouses, do you have an area you'd like? For the guesthouse, do you have one in the moderate price range that includes free parking? There are 12 options for moderately priced guesthouses, any area preference? The area doesn't matter. I just need one with rooms available for 3 nights starting on Friday. For how many people? I need it to be for 2 people. The Acorn Guest House on 154 Chesterton Road should be sufficient, shall I reserve a room for you now? Yes, please, and I'll need the reference number. I was unable to book that room for you. Can we try a shorter stay or a different place perhaps? Sure, please try 2 nights. The booking was still unsuccessful. Would you like to try a different day? Could we please try a different hotel that is close to The Acorn Guest House? 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? Well I guess I'm out of luck, unless there are hotels in adjoining towns I could try. Sorry, we only work with places in cambridge. 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. I could not book a room for that number of nights on those days in that area. Perhaps try a different area? Please try 2 nights on Friday and see if that works. For a guesthouse, please. 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?
