I'm looking at booking an Oceanview cabin on Deck 5 on the Prima, it makes me a little nervous because of what's above it on the 6th Floor (Theater & Club, Casino, Cagney's, and Commodore Room), but sounds like at least the Casino area wasn't noisy. What was your cabin number? We might try to get one close to yours since you had a good experience.
Anyone else have experience on staying on Deck 5 that might help us pick a good cabin on the Prima? Thanks!
