I'm not sure about a sealant coming. Seems to me you'd do that before drilling the railings in, plus the platform safety striping is already in place which, again, I'd think a top coat would have gone down first. But I'm not an expert so maybe it's still coming.
Either way, it's baffling they didn't go with a tinted concrete like they do basically everywhere else across the resort. A gray or light brown would have helped the overall appearance immensely.
I do like the lights on the columns though.
