Would you help me book a train for Thursday, please?
Yes, where would you like to go to?
I would like to go to Cambridge
There are over 200 trains going to Cambridge on Thursday.  Where will you be departing from?
I will be leaving from Kings Lynn.
That narrows us down to about 19 trains. Do you have a time you would like to leave after or arrive by?
I would like to leave after 15:45.
Then in that case, I recommend the TR0209	which departs from Kings Lynn at 16:11 and gets into Cambridge at 16:58. Would you like me to book it for you?
Yes, please. I am also looking for a place to stay, ideally a hotel with a 4 star rating in the moderate price range.
There is nothing in the price range you mentioned.  Would you be willing to stay at a cheap hotel or an expensive hotel?  
I would like a cheaper hotel. 
Ok I Am going to book a cheaper hotel for you ,have a good day,thank you.
I still have some requests for the hotel, before you book it. 
Okay what can I do for you?
I need you to find me somewhere to stay with a 4 star rating in the east, moderately priced, and with wifi. Type doesn't matter.
There are 3 in the east area. Do you need free parking?
That doesnt matter. Choose your best recommendation and please book it for 2 people on thursday for 5 nights. And do remember to send me the reference number

I think that covers everything. Thanks for your help.
