The noise map only crew members have

Guest services team, Celebration. We have an internal document we call the noise map. It marks every cabin on every deck that has a known noise source — engine vibration, ventilation hum, proximity to public venues, structural resonance. This document is not public and guests cannot access it. However, if you call guest services before your cruise and specifically ask 'Are there any known noise issues with cabin X,' we will check the noise map and tell you honestly. Most guests do not ask. The ones who do sometimes get moved to better cabins preemptively. Cabin 10100 is on the map for very mild ventilation noise that ninety percent of guests never notice. The ten percent who do always call on night one. If you are the ten percent, ask before you board.
