unfortunately, we ended up canceling that cruise due to covid.
We did end up on Odyssey in 2022, but only 2 of us sailed, so I don't know about the 3 person cabin.
I can tell you that we have had a few cabins near the elevators on Oasis & Voyager class ships, & have not experienced any noise due to the proximity to the elevators & stairs. In fact, they have become some of our favorite cabins due to the proximity to the elevators & stairs.
