While surfing through another web site, I found a URL for
Live Ships Map - AIS - Vessel Traffic and Positions, that tracks ships, including cruise lines. While it's not world wide, it does show the Cape Canaveral port. Here's the URL for that:
Live Ships Map - AIS - Vessel Traffic and Positions
Right now (Sat morning 0720) it's showing the Disney Magic and Carnival Glory in port, and you can click on a ship and see it's track, etc. I can't seem to find the Wonder, though.
