That would either be cabins or staterooms.

All staterooms on the Royal Caribbean Rhapsody of the Seas offer a telephone, television, private bath, shower, vanity and hair dryer. There are four categories of staterooms available. Depending on which you choose, your stateroom may also include a whirlpool tub, private balcony and mini bar.

There were 416 first class staterooms.

Second class staterooms weren't as flash as the first class staterooms. You would have a library, Smoke room, promenade deck, There would be people from different countries aboard. You would be back at the stern during most of the voyage.

The first class had better staterooms and more rooms than the third class. Now the third class just had small tiny cabins near to where the iceberg hit. So they had to have felt the shudder first. The first class rooms where more far away so just a few heard or felt the shudder. Some didn't feel anything, but they found out soon enough.
