Is there any 'baby swap' at Sea World, Aquatica, or Busch Gardens?

I know Disney has a system set up so that one parent can wait with a the kids too small to ride, and then they swap, and that way the parents don't have to wait in the long line twice. Does Sea World/Aquatica/Busch have anything similar?

Or if not, is it ok for the whole family to wait in line, but one parent ride, then the other, and the kids just walk out exit?

Kids have to be about 7yrs old to be by themself while in the park. So if your kids are younger than that, they do need some one over 16 yrs of age with them.

And yes, you can get a rider swap pass, but unlike at Disney where you ask before you get in line. You get it after you get off the ride. But it's the same as Disney and allows up to 3 people ride with the pass.
