I am taking the kids to watch football at Wembley at the end of the month and I don't know how best to get there? We are coming from the West up the M4. I am not sure if driving close would be a good idea as would be 6pm ish so likely busy on M25? Is there somewhere easy I could park and get a tube to Wembley or is that just making much more travel time? Trains don't work for returning home time so I think I have to drive.
