Yip depends on what facilities the club have like swimming pool,squash courts,sauna ect ect.
Richards Bay club has a swimming pool and 2 x squash courts with 2 studios 1 for ride classes and 1 for general stuff like stretching and kickboxing and stuff like that and the fee is only R420 per month.
I know Comaro View Virgin Active is R300 per month.
So it really depends on the club. Make a quick call to your nearest club and press the option for sales. Just ask them what the club fee is without any loyalty programs.
