Rachel,
I wouldn't mind betting many of us have taken a video dressed like that but in the privacy of our home, I know I have when I borrowed a very short leather skirt.
As for the walk, I commented about GGs attempting it, I saw it first hand on my last cruise, some of the younger passengers were wearing 5"+ heels they didn't walk as well as the person in the video, especially on the sweeping stair case, the only difference is there were quite a few guys waiting on the edge of their seats to catch them if they did trip, that's something a CDer might not be so fortunate about. He would probably be face down hoping the forms were still intact.
While Lorileah said no rules had been broken maybe it should have been posted in the media section. Lets be totally honest it was done for the thrill factor to see how much attention could be drawn. A GG would have attracted as much attention but possibly have not got the WTF looks when they realised it was a guy. I still find it amusing at the check out when the circle became wider when they realised what was going on.
Ok going back to other point it could have been part of a Candid Camera stunt and the public were asked after if they had any objections appearing in the video.
