Has anyone taken the "premier" class train from Durban to Johannesburg ? We're 2 families of 4 each in Durban for 3 days for a WC match in June 2010. Then, we need to catch a flight out of JNB for Victoria Falls. Trying to determine whether the cheaper train tickets for an overnight sleeeper from DUR-JNB will be worth it when compared to one way flights. Can you actually "sleep" on the train ? How's the food, etc ?
