I suffer from allergies - not terrible but enough -- and they were REALLY bad in New Jersey. But in Naples, not so bad. Wouldn't worry about mold - never had a problem with that. On "high pollen" days I might get the sniffles now, but NOTHING like Jersey. It's worth it. Nothing's cheap down here, but there's a reason why ppl keep coming down here in droves. And not just for vacation anymore - but to stay permanently.
