Hi Carol. My brother and Sister in law are Brits, now both 70, and they've been doing these trips for years without problems. They use proper organised camps, mostly similar to say U.S. National Park RV parks but sometimes with luxury facilities. It is probably no more dangerous than an RV tour of Florida. Jean and I are probably going with them next African summer so I'll let you know how we wimpy Brits get on with it.
