And what I've attempted to share and you continue to ignore is that at Alila Napa Valley guests have actually (not theoretically) shown up with kids and they've been allowed to stay. So apparently some have actually "argued the kind of thing I'm suggesting" and did in fact win said argument. Furthermore, in this very thread there seems to be a data point suggesting there may have been below 18 year old guests staying at the property we are currently discussing (though I fully acknowledge that isn't clearly confirmed and may be inaccurate)

I'm not entirely sure why you are expending energy attempting to argue that this can't happen given Hyatt's exceptionally accurate booking engine, when it actually does/has happened at another property in the same brand.

Anyhow, I'm done debating you on this one, we can agree to disagree. I think we've clearly established this is an Adults-Only property, it's time to move on.
