Sorry I can't help you; I have no ideas about your questions. But I am interested in responses to your JNB airport hotels questions, and would like to add one of my own.. It seems we will have about 10 hrs between flights in JNB (10am - 8pm). Since I will be alone with my two daughters (ages 12 & 14), I was wondering how to kill time safely.. Any suggestions? (we will just have finished two red-eyes, and connecting to a third, so trying NOT to sleep, lol)
