Let me start by saying that this could easily be the best large cruise out there but RCCL has totally messed up the marketing and roll out of this ship.
Here are the good points:
**The public rooms - like Two 70 is fantastic (except for the ackward stairs)
The cabins on the Quantum are first class. The beds are fine (don't listen to the others), and the shower is fantastic for a cruise ship. New chairs on the balcony are nice but for some reason RCCL forgot the lights on the outside of the balcony. The room service menu is minimal and the overall room stewards are ok, but not exceptional.
