Can you help me find a train leaving after 9:15 going to Ely? Thanks.
Yes, there are many. Where are you departing from?
I am departing out of Cambridge. I really do need to leave sometime after 21:15 for sure. 
There are 14 trains available. What day will you be leaving?
I'm leaving on Saturday.
I have two on Saturday. Would you like me to book one?
Yes please. I need 6 tickets.
I have booked 6 seats for you on saturday.  Would you like some restaurant suggestions in ely?
Thank you. I also need a hotel.
Where would you like to stay on your trip?
First, can you give me my reference number for the train?
Yes, the Train ID is TR7738.  
Thank you. I need a hotel with free parking and free wifi.
I'd love to help you with that. There are so many hotel options in the area. Can you help me narrow it down a bit? Area? Price range, etc.?
I would like a place like a guesthouse that has at least 4 stars. 
We have 16 possible guesthouse matches with parking and internet.  What price range are you interested in?
Sorry can we go back to the train for a moment?  I need the reference number, not the train ID for my booking.
Your reference number is  DALA684J
Back to the guesthouse now ... what is the price range for your favorite one?
the arbury lodge guesthouse is quite nice. It's cheap too.
Thanks, that's all I needed today. Goodbye!
You're very welcome. Have a great day. Goodbye.
