I need a place to stay that includes parking
Would you have a preference for an area or price?
A hotel on the east side with free internet and parking if thats doable. 
I have one hotel on the east that offers both free wifi and parking. It is the Express by Holiday Inn Cambridge. It is expensive and has a 2-star rating.
I need the postcode too.
The postcode for that is cb13lh. Do you want me to book a room now?
No thanks, but I'd like some information on a train next.
i can certainly help with that. Where are you departing from?
I am departing from cambridge and need to arrive by 12:00. 
We have over 400 trains that meet that criteria, what destination did you want to go to?
This will be on a Friday and I'm going to Leicester.
Is there a time you want to leave by?
I would like to arrive by 12:00, which ever one is closest to that.
I have the TR7505 that will arrive by 11:06. Would you like me to book that for you?
Yes!  Please book for me and three friends.  I need the reference number as well.
Booking was successful, the total fee is 151.19 GBP payable at the station. Reference number is : A6Z2U9VN. Is there anything else I can help you with? 
No, that should be all.  Thank you!
You're welcome, and have a great day.
