Nice little guide just arrived from Wolves. Where to drink, don't be nobhead etc and from 5.30pm Shuttle Buses are running Wolves fans to the Stadium (police escort). No mention if they are coming back after the game, hope they are
My guide is clearly better
Still, 5:30 sounds awfully early. It will take you 15-20 minutes to get to the stadium by Bus and then you ll be probably confined there until the game starts, you ll be throwing away your entire afternoon.
