Thanks, Rick. There is actually more to the story! Seabourn markets it as a 21 night cruise, as well as three 7 night cruises. So what if you booked it as the 21 night version?
Another example I have: suppose you are on a 100 day world cruise that has 15 different segments. Does this mean you have to attend 15 muster drills? No doubt by the 3rd drill the crew could take a break and let the prior passengers supervise the drill for the newbies.
