Travelling To Wembley Stadium

[bednobs]

hi, i am going to wembley stadium on saturday to a concert. Ordinarily, it would take me about 1.5 hours to get the general wembley area. How much EXTRA time will i have to leave? I am parking at the stadium too.
Also, i never usually go to concerts - the doors open at 4:30, first support act is 18:30. Do they let you go in while the support act is on? How much time does it take to actually get in with security and all that?
Lastly, are there shops/restaurants on site?? ie if i were to get there early, will there be something to do?
i know i probably asked all this before!

Yes, you can go in while the support act is on.
