Being a retired couple from the mid-west and enjoying the Gulf Coast either before Memorial Day or after Labor Day was our rule of thumb. Not so much any more, between spring and fall breaks and the year around school and their frequent breaks, there are families with children every where. And you never know when they'll be there. Don't get me wrong, I think it's great that kids get introduced to the wonders out of doors. My parents took me CAMPING when I was 6 mos. old, just turned 70 the other day, and still loving it. And I should not complain about the families with youngsters being the only reason for crowds at the parks. I AM A BABY BOOMER and we're totally consuming the camping space. More of us hit the road every day.
So with that said my advice is to have a Plan B.
