The riptides are definitely dangerous. You can check out WMBF News online to see all of the issues we've had as of late.
I can't imagine a 1 yr old or 6 yr old would be going in farther than their knees, so they are "safe". The older ones are the ones you really need to be concerned about. Pawleys Dude gave you great advice. Unfortunately, many of the lifeguards don't always speak English well and that seems to be a potential issue, as was mentioned last year after the season was over.
Honestly, I'm saddened every time I hear of a drowning or a near fatal one. Then again, we're hearing of it in the pools, too. I think maybe people are taking chances they just don't need to take, for the sake of having "fun".
Enjoy your trip but do it safely
