Asuming I read the vehicle's registration number correctly, a small minibus type coach was in Park Lane a few minutes ago, on the layover (at Stands A-G). Its reg was T200 OCT.
I'm assuming it had something to do with Megabus on the basis that the vehicle had seats which had a Stagecoach beach ball moquette.

Nothing particularly noteworthy - just thought I'd give it a mention.
