they will post, i had mine post to NW and it took a couple of weeks.

As far as the Simba lounge its horrific at beast. NBO has another lounge simply called VIP which is MUCH nicer and at part with JNB skyteam lounges. However its an airport run lounge and not sure what you need to do to get in. We were escorted by the airport official wearing a yellow traffic control jacket which also wisked us through without clearing immigration or just walking by when the guy just gave him a salute of some sort... quite strange. It is at the farthest end to the right, just ahead of the smoking area and stuck in between two souvenir type shops, check it out.
