I'm looking to get on a train on Saturday.
From where to where?
I'm leaving from London Liverpool Street and I need to arrive in Cambridge by 09:30. 
the TR2503 will get you to your destination at 9:07.
Perfect. Can you book that for me for 3 people?
Booking was successful, the total fee is 39.83 GBP payable at the station. Your reference number is YSVSLY1L. Is there anything else you need today?
I also need a hotel in the East. 
Do you need parking at the hotel?
