Greetings from a Space Port local.
First, as you know, the Disney pier supports both the Magic and the Wonder. To the left, but hardly ever seen in this webcam, is where the Royal Carribbean Sovereign of the Seas is docked. And to the right, again, hardly ever seen on this webcam, is the Carnival dock that hosts the Fantasy and the new Spirit.
Sometimes on this webcam you will see the SunCruz Casino ship at dock (usually to the left side of the cam screen).
Also, on shots when you see a Disney ship, you'll also see a white ship in the lower right. I have no idea what boat this is - it seems like a derelict as it has been there for years.
If you have lots of time on your hands, take a look at the Cape Canaveral Cam at
http://www.twopalms.com/ . It is near Jetty Park and overlooks the ocean towards the entry channel to the port. If you time it right (5 - 6pm EST) you'll see the Disney ship and others leave port. Updated every 10 seconds or so. Enjoy
