Laurie, you do know that red tide can be active at some beaches and not others? And you mention one specific beach on Captiva. Sorry though that you had the problem, but it was one beach for a few days.
Yes, I do understand that. When the air was really bad on Captiva (at the beach where the 2 islands join, all the way up to the point - we did go out in search of a better spot), it was present in the air but much milder on Lighthouse Baach on Sanibel - but that's where all the dead crabs were. As we walked around the point there to the other side, couldn't feel it. As I understand it, the blooms have been offshore so it will depend on how the winds are blowing, and possibly how much moisture the air is carrying. On the worst day on Captiva, there was heavy mist blowing directly inland, at the beaches droplets of water were visible all day.
I personally wouldn't cancel a trip, as long as there were other reasons to come here besides just beach and pool. But if I had a child with asthma, and my resort were on the beach, and beach + pool were the sole reasons for the trip ... I'd keep checking the maps before springing for the airfare, but the maps do look pretty good at the moment, unlike last week. I just can't adjust for whether this can trigger a more severe asthma attack in a child (or adult), since for me the effects went away when I went inside. And obviously things can change by the day and by the week, in either direction.
I'm writing this sitting on our screened lanai at Ft Myers beach. Breezy day, wind is blowing from the south. No probs.
