I've always found it odd how many cruiselines have ships with the same name. At least Royal throws an "of the Seas" at the end of the name. What really is fun is when two ships with the same name are in port together. You get in your taxi to go back to the ship and the driver says what ship - oh...the Dream...and you end up on Carnival Dream vs. Disney Dream.
