AS said above, it will also depend on the age of the ship and it's design. I've been on two Voyager class ships, Mariner and Voyager OTS. Voyager was an older design and the dividers were basically steel as a part of the ships super structure, where Mariner has plexi-glass removable dividers. I think someone else has posted earlier that the newer cabins were more outside the ship as some of the older ships had the cabin more inside the hull. Radiance OTS also did NOT have removable dividers. There are also SOME rooms which have a connecting door between them, again depending on the ship. Either way you'll have a great time!
