I've heard sealice is a problem near Pelican's Plunge. I don't think the other beaches have issues with it. If you plan to be over at Serenity Bay (I believe that's the adults beach and where I would be if I didn't have kids) then you are probably fine.
I've also heard if you rinse off (you have to take your suit off, insert joke from Joe) after you get out of the water that it rinses them off of you and you are ok. Something about they get under your suit and can't get away so they just keep stinging you.
I don't want to risk it with the kids. Cause if it's going to happen, it's going to happen to my overly dramatic 7 year old. They also say to bring vinegar to spray on any stings. I will have that as well as these Wipe Away things. Can't be over prepared!
If anyone has an issue, hunt me down!
