An Army NCO I once knew had a favorite saying - "Fluid isn't flexible enough, go for the vapor state." It goes well with the traditional Army joke, "Semper Gumby!" (Always Flexible in cracked Latin).
It sounds like you are having fun, even with the requirement to be flexible. My wife and I will be on the NA next January in the Caribbean, so I am very interested in your reports about the ship's condition, the staff, and the amenities - thank you for posting this.
