The last time two Disney ships arrived at Castaway Cay on the same day, it was quite a battle for the dock. It's not widely known, but the lifeboats on the ships camouflage cannons and torpedo launchers. The ships began firing at each other and both hulls sustained damage. A crew from the Magic tried to sneak up on the Wonder in a tender boat, and the tender was hit full-on with a torpedo and sank. At that point, the captain of the Magic surrendered and allowed the Wonder to use the dock. If you go snorkeling, you can still see bits of the blown up tender boat.
