I would be very upset too. In my opinion, Norwegian should not be selling this stateroom until the severe noise problem, which they know is an issue, is fixed by installing soundproofing. Even if research was done, nobody would expect that a "noisy" room, especially at the penthouse level, would be so loud the occupants can't sleep at night. If I paid $10,000 for a stateroom I couldn't sleep in, I would be livid.
