I'm looking for a hotel with free parking in the north.
Yes, I can help you with that. What is your price range?
I would like a moderately priced hotel. Preferably a guesthouse.
How many stars would you like it to have?
That doesn't matter. Can you book a room for 4 people at your favorite? We'll arrive on Friday and stay for 3 nights.
I will go ahead and book you at the Archway House. Booking was successful. Reference number is : GJA79LYP. Is there anything else I can help you with today. 
Yes I also need to find a train going to bishops stortford.
Could you tell me the day you will be traveling, and the time you would like to leave?
Yeah, we need to leave after 15:00 on Sunday from Cambridge.
TR3600 leaves Cambridge at 15:29 and arrives at bishops stortford at 16:07. Do you want to book this train?
Yeah, get me 4 tickets please and then tell me the reference number
Booked! Your reference number is ZQ7T3ROI. Anything else you'd like me to help with?
I am all taken care of now. Thank you! See ya!
Okay, goodbye and have a nice trip!
