Vince,
Don't worry that you will be experiencing anything near what the CDC article reported from those hotels. First of all, your pool is outdoors. The air circulation outdoors is far better than found indoors, especially since energy efficiency has made circulation rates lower indoors. Also, outdoor pools are exposed to sunlight and the UV rays in sunlight break down the chloramines. Finally, notice how many people were in the pool and spa -- extremely high bather loads that simply overwhelmed the air circulation system (and that system was shut down at one of the hotels). I doubt that you will ever have anywhere near that many people in your own pool, even with a pool party.
My only point was that one should not assume that commercial or public pools are all well maintained. For indoor pools, I think it's pretty important to use a rather narrow range of CYA -- a small amount of around 10-20 ppm. Most indoor pools don't use any CYA and therefore overdose in disinfecting chlorine which degrades swimsuits, hair and skin (my wife complains about that when using a community center indoor pool during the winter, for example) and also may produce more of the nastier disinfection by-products (dichloramine and nitrogen trichloride). At the other extreme, having very high CYA levels leads to slow breakpoint so a buildup of monochloramine. A proper balance of a little CYA would be a good middle ground, though for these hotel incidents they simply had too many people using the pool and spa at one time so that would be hard to handle even with proper chemistry (though proper chemistry would be better than not).
