I agree that it’s best to let the cabin attendants manage the switch. They know who is moving, and they coordinate with one another. We had to change cabins for the first time on our recent b2b. It went very smoothly. As directed, we left clothing on hangers, and packed everything else in our luggage. We kept valuables and items we thought we might need before having access to our new cabin with us. We used our cross body travel bags for this purpose. We left our packed & locked luggage in the middle of the room and exited our cabin for the last time before breakfast. After breakfast we reported to the b2b meeting location. Once we had obtained our new Sea Passes, we enjoyed roaming the nearly empty ship before enjoying celebratory cocktails🍹🥃 When we entered our new cabin, we found our clothes neatly hung in the closet, and our luggage lined up near the veranda.
