I don't believe it given the slow traffic approaching the Dartford crossing and again getting into Norwich.
2.5 hours would indicate averaging just over 70mph with zero delays.
Does this mean coaches arriving early will have to fill in time by driving around the Norwich tourist attractions. So a drive past the Castle and a u-turn and a drive past the Castle (repeat until 1745)
No email so far, still scheduled to be picked up at 12.30, being picked up at 14.15 doesn't sound good, and I would look to record the Sky coverage so you don't miss anything.
