Obviously your name says it all. But I disagree a ton with the skin and eyes thing and I can find a ton of articles to back me up, the below is just one.
Going Chlorine Free: The Pros and Cons of Salt Water Pools
We had a Chlorine pool with all this fancy stuff to prevent from putting a ton of Chlorine in, which worked, but it was still more harsh on our eyes than a salt water pool. But commercial pools tend to not have all the fancy add ons and our eyes are killed in almost all chlorine if not all chlorine pools I have been in at hotels. We never have any issues with salt water pools.
As for the feeder thing, I imagine in a SWG pool they are not used much as you can keep a salt water pool balanced easier than a Chlorine pool. Which is why at hotels when it is salt water I don't smell or feel the effects of a traditional chlorine pool. I doubt the feeders are used that much.
ETA: My daughter has never been wrong. I thought she was crazy the one time because she would only go in the one pool at this resort we were staying out. Only to find out later it was the only SWG pool on property. I thought they were all Chlorine.
