I think alot of places do saturday swimming lessons. I'm not sure about Sunday. I didn't manage to stumble across any.
I know Aqua stars at Warners bay, fitness at vikings at elermore vale and there is a place at a squash centre in wallsend (council street) they all offer saturday lessons. I'm not sure if it's restricted to particular age groups or not but they might be worth a look?
