spending a night at J´burg international airport is not one of the best thing except if you are booked at the Intercon.
i think the best is the massage palour, it has whats called ``aqua massage``. your body sprayed with water as you lie down.
not naked of course and not like those dingy joints in down town Nairobi where massage can be misataken for other things but pure massage.
its done in full view, though you have to enter into the machine that dispenses water and the whole ceremony begins.
there is also massage on the chair which is also good. so if you are stuck at the airport, make sure you have extra rands.
