I was on the Dream this summer on a 5 night 4c and a 3 night T.
Concierge crew members had family with children living with them. And there was a husband/wife set of crew members. When I was at Port Canaveral a young lady was boarding and was to visit a crew member for 10 days...so I don't think they all share cabins...possible some might double up to save money?
I do think too that on some of the decks like deck 7 crew members had quarters so not all are living below deck. I do think they all work very hard and I basically doubled the suggested tip amount except for the head server gave that person 50% more.
There's a hierachy for the rooms......
EDITED TO SAY: NOT ALL OF THIS IS TRUE ON DISNEY, BUT ACCORDING TO THE BOOK ABOUT OTHER LINES:
Obviously the Captain has his own nice quarters, with a staff to serve him. He takes his meals in his room, or anywhere else he wants to.
Ships officers also have nice rooms, often similar to a one bedroom. They take their meals in a reasonably nice dining room, with good food.
Cruise Director, Social Host (if they have one) and Art Auctioneer have what is basically a one bedroom. They also dine with the officers.
Some of the stateroom hosts and concierge have rooms tucked inside the hallways of passenger areas, so they're closer to the passengers when needed. But I've seen those hallways...tiny!!!
The rest of the crew share rooms below and have a crew dining room, where they are not waited on, and the food is not the same (At all!) as what is served elsewhere.
The musicians and entertainment staff can choose to eat in the officer's dining room, but they still have to share a room. ON
DCL, THESE PEOPLE DON'T HAVE THE OPTION OF EATING WITH THE OFFICERS, THEY ALSO EAT IN THE CREW MESS.
Everyone shares a room except for the upper level officers and CD's. Married couples are allowed to share a room, if there's one available.
Their rooms are "free", so doubling up isn't a matter of saving money, for the most part, it's the only option.
I talked to a CM who had to be at least 6'8" tall, and asked him if he got his own room because he was so big, and he laughed at me. He said, "Nope, I have to share like everyone else".
