What's the best conversational icebreaker when you are on a cruise?

The weather? No. That's really only the concern of the captain, and the rest of us were usually in our cabins avoiding the heat anyway. The meals? No. They're all pretty similar; defrosted meat and tinned vegetables. Movies and the news? No. They're not available in the middle of the ocean.

Remember. The answer is and will always be this: Dolphins.
