Are there many places to stay with mid-range prices?
Yes, we have several options! Do you have a star rating you'd like to have it be?
Yes, a 3-star guesthouse would be perfect. Free parking too, please!
There are three 3-star guest houses in Cambridge. Is there a part of town you were interested in staying in?
No, I don't have a preference. Please just pick one, and book it for 4 people, 2 nights starting from wednesday.
Okay I have booked you into the Bridge Guesthouse and your reference number is UV8VFH1S.
Thank you very much.
Is there anything else?
Yes, I'm looking for a train the same day that will be going to Cambridge.  Can you help me?
Sure, I can do that for you.  Where will you be departing from? 
I will be leaving from Kings Lynn after 16:00.  
There are 8 trains that leave Kings Lynn after 16:00. The earliest leaves at 16:11. Would you like to book this train?
no just the id please
The train leaving at 16:11 is ID# TR5153. May I help you with something else?
That was all that I needed to know, thank you!
You're welcome! Have a great day.
