I was relatively sure the access rules had recently changed but, according to the website, that doesn't seem to be the case (FYI - Silver members have been allowed access since the very beginning). Enjoy then and, in case you struggle to find it, you should take a left turn as soon as you are through security, look for McDonald's and go down the stairs (on your right) just past the restaurant, the entrance will be on your right-hand side (the lounge is at tarmac level ).

@fifty_two: can you confirm that Silver members are still allowed to enter?
