The Quantum is a beautiful ship with some awesome built in amenities. The seats in the Royal Theater have vents along the backs to help keep the temperature comfortable throughout. All the different cabins we visited had well-distributed vents above the cabinetry and intakes distributed below.
Although we stayed in one of the less expensive cabins - an oceanview - we did not feel RCI cut the built in amenities in our room. As I have posted elsewhere, there are even hooks in the shower for your scrubbies and back scrubbers. The makeup mirror over the little desk/makeup table has wonderful lighting for doing your makeup. We got to see quite a selection of other cabins, and I have to say every one was as wonderful as the last. For those wondering about the Junior Suites, there are at least two layouts and we were impressed by both.
The real jewels of this ship are the staff. I can't say enough about our room steward, Ryan, for taking excellent care of our 3rd floor cabin. If you go to Silk, ask for Nemeesh. He provided such an excellent experience, it became our favorite restaurant on the ship.
Much larger with more amenities and storage than expected.
