No there was no escort two years ago and it took forever I seem to remember because the way out is back past the stadium. Two years ago there was only about 4 or 5 coaches as well - and I'm pretty sure they charged about £25 a coach to park
Don't forget the walk from the coach drop off to the ground, about 10 minutes I think from two years ago - after the game will take AGES to get out of Norwich, I'm fully expecting to be indoors at about 4am
