dinning service teams work six months on and two off, it is never six on six off so no, they do not work half the time. even the shops crew sail mostly with six months contracts and two off then back on. plus most of the staff know each other and tend to talk about 'what went on while I was away'. it is not inconceivable that what the server has said is correct.There are a couple of things that can be deceiving about these numbers. First of all, any particular crew member is on board at most half the time, as they work for a multi-month contract, then are home for at least the same period of time before starting the next contract. So, even maiden-voyage crew members will have been on at most half the sailings.
Then there's the issue of passenger counts vs staterooms. The Dream and Fantasy have 1250 passenger cabins, and a passenger capacity of 4000. So, those ships can sail at capacity only if there are an average of 3.2 passengers per cabin. If you have a lot of people traveling as couples on a particular voyage (which may be the case when school is in session in most places), then the vessel can get to the point where every stateroom is booked, yet there are hundreds of people apparently missing from the dining rooms. From the MDR's perspective, all that counts is head count, so they may perceive that a particular sailing is way undersold even if every stateroom is occupied.
I can see this issue potentially becoming more of a problem as time goes on. I suspect that there are a lot of people that would never consider booking a DCL cruise unless they had young children sailing with them, thinking Disney is "only for kids." But, they may go on a sailing anyway, either as grandparents or others on an extended family trip, or as parents who eventually become empty-nesters. At least some of those people will like the experience enough to rebook without kids the next time, often staying just 2 to a room. As more and more of that passenger demographic accumulates over time, it makes it harder and harder for DCL to fill the ships to capacity. One way that could address that from a revenue standpoint would be to raise the fares for the first two passengers per stateroom, and reduce the fares for additional passengers. Families could end up paying about the same, while double-occupancy cabins would pay more.
i agree with you about your comment about the issue of passenger counts vs staterooms. the thing the server was mentioning is that the sailings have never been that low so regardless of how many cabins were occupied the numbers were, in her opinion, the lowest she had seen. it still lowers the $$ amount Disney collected for that sailing even if all cabins were full and doesn't change the passenger count of 3500.
while you suspect that there are a lot of people that would never consider booking dcl unless they had young children i suspect that there are just as many that would. us for example. last year it was us and our two grown sons and their significant others but no children there either. i see lots of couples who are on board, just the two of them, in fact there's a lot of posts by those people who want to know what its like without children.
i find it all very interesting and i think we can both agree that time will be the deciding factor in all this. i just wonder if they are seeing a down trend already. maybe, maybe not.
