Sometimes the ladies are right! I presume they would have allowed a refundable deposit, in case you didn't like some aspects of the car?
Back to the tour, just spoke to Lotus and the Heritage tour normally takes about 2.5 - 2.75 hours. Normally finished by 17:00 at very latest... So B&B booking in should be OK without arranging 'out of hours' arrival.
Table for 5, in the room with the carriage seats, is booked for 12:15 - 12:30, in the name of Wright, at the Station Bistro.
