Sadly dreadging Simpson Bay for a new cruise pier will change the way tides and hurricanes come together. Creating new disasters from unthought of issues.
As for the Royal Caribbean Disneyland, they are creating a private island for passengers on St Maarten. The point of cruising was to see new places, this will be lost. They have more crap than a Christmas turkey to do on the ship, the don't need a theme park pier.
