You bet. The question is probably not where I did but where I didn't. I have pictures of the stateroom, pictures of the restaurants, pictures of the lab, by the pool, even in the pool!
Most of the time my 35MM is hanging off my shoulder (when it isn't pressed to my face that is!) I also bring along disposable waterproof cameras. I have a great one that my DD took on our last cruise of DH and me in the Goofy pool. He had just popped up and grabbed me in a bear hug and she caught us like that, laughing our heads off with the smokestack in the background.
So take the camera with you at all times - you never know when that perfect shot will pop up. Oh! The MUST shot is in front of Lumiere's or Triton's with Capt. Mickey or Ariel (not sure which ship you're on).
