I have just been on the Jewel on Deck 11 right under the Gym. Interesting what new cruiser wrote, some of the tread mills were "out of order" for some days, but running again after 2 or 3 days. Luckyly we still had no problem with noise, I was afraid of it. But it might be, that the tread mill above our room was not used (the gym was never very busy) or we got up early enough anyhow. But also during the day I never realized something.
