I need to get to Cambridge by 10:30, is it possible to do that by train?
Where are you leaving from? And what day do you need to leave?
I'll be leaving from Ely on Monday.
We have three trains arriving by 10:30. What time would you like to leave?
What time would I need to leave in order to arrive by 10:30? 
I would say you should leave by 09:35
Ok can i get the train ID and price?
TR2987, fare is 4.40 pounds and your trip will be 17 minutes.
Great. Thank you. I'm also looking for a moderately priced, 4 star hotel. 
There are many to choose from. Do you have a preferred area? 
I don't have a preferred area, but I am looking for a hotel, not a  guesthouse. Does that narrow it down?
Unfortunately there aren't any hotels that match that criteria.  They are all guesthouses.
Ok, a guesthouse will have to do. How many choices do I have? 
There are 11 choices.  Picking an area of town will help to narrow it down.
Please pick the best option. I need a room for 8, for two nights and starting Monday.
Booking was successful for the a and b guest house. Your reference number is : 1HPJ1F1W.  Do you require any further assistance?
Not, that is all I will need today. Thanks. 
Is there anything else?
no that will be all thanks so much.
You're very welcome. Have a good day.
