Sure, Sodwana is a totally different experience but I still think R600 is extortionately expensive - even if you get coffee, snacks and a seal snorkel. Especially when you consider that other Cape Town based operators offer dives in the same ocean, looking for the same seven species of shark, using the same amount of petrol etc. - for a third of that price!!!
Don't get me wrong, I can understand that some companies ask premium rates when they offer a premium service. I get irked by money printing businesses though who offer service not significantly different from so many others but somehow can justify to ask rates three times as much - trusting that the foreign visitor won't know any better. I've seen nothing on this webpage convincing me that this operation is not the latter.
