Yes.

Lots of the advice that has been given out has been contradictory tbh. Arrive before the road closures - so 2h before KO - leave an hour after FT has been general advice. You can't leave a car on yellows, Blue Badge or no, for that length of time as you say. Aside from the fact that many can't hang around for that long anyway.

There's been a clear lack of a plan. The wristbands being announced on the Wednesday before the game speaks volumes tbh.
