I need some help choosing a train from Cambridge to London King's Cross.
The next train leaves Cambridge for London Kings Cross on Friday at 05:00. What day do you want to travel?
I need to leave on Wednesday sometime after 16:30. 
I have a train leaving at 17:00 and arriving at 17:51 would you like to book this?
Yes please make a booking for 3 people. 
The booking was successful. Reference number is : IGMRVY4Y
That's lovely. We also require lodging. Could you help find a guesthouse with free parking?
There are 21 guesthouses that include parking. Is there a price range or area you would like to stay?
It doesn't matter, we will also need wifi, and will be staying for 2 nights, starting on Monday.
I would recommend the Alexander Bed and Breakfast then.  
That sounds great.  Can you go ahead and book it for me?
Alright I booked it. Reference number is I5AR5Q3J
Thanks so much! I'm all finished now, goodbye!
Your welcome! Please have a nice day!
