From the Cruise director come the top 10 dumb questions asked by passengers.   10.  Does the ship generate its own electricity? (Or is there a long extension cord reaching back to the dock) 9. At what elevation are we sailing? (For those of you who do not know, ocean vessels sail at sea level!) 8. Does the crew sleep on board? 7. Is the water in the toilet fresh water or salt water? (Does it really matter?) 6. Do the stairs run both up and down? 5. Is there music in the disco? 4. What do they do with the ice sculptures after they have melted? 3. When the ship's photographer takes our picture, if the pictures are not numbered how do we know which one is ours? 2. Which elevator do I take to get to the front of the ship? The number one question requires a moment of explanation.  On one particular ship the carpet in the elevators has the day of the week on it and is therefore, replaced everyday with the appropriate day's carpet.   When informed of this one passenger inquired: 1. Do they change the carpet on each floor?
