A couple of things to consider with slow sales is how people can actually get to Wembley
Drive - fine but you need that designated driver, parking etc
Train - expensive, unreliable, no seats, two northern clubs going so demand will be high
Coach - no drinks allowed by law, can be a slog, toilets an issue for the women, service stops can be entertaining putting it mildly and now coach companies taking the piss with prices they are setting. Not helped by City charging £50 a seat.
£50 x 49 seats = £2450 - no way should a coach company rake that in.
This means other firms who take independant fan groups see pound signs. I do a coach to most away games and the price to London normally is a good £500 less on average.
Then the parking at Wembley for a coach is also £120
It used to be £50
Semi finals should not be at Wembley
