Best deck for oceanview to not feel waves on the Oasis class?

[xps15z]

I've never done a oceanview or interior. What are the best decks + locations for Oasis class to not feel the movement of the ship/waves?

I've only done balconies on Oasis, decks 6-12. Only once I have felt the motion of the boat and that's when I did Boardwalk which was located at the back of the ship, and I said never again lol.

P.S. This question is for a family member btw who are cruising for the first time and doesn't like motion at all. I am just presenting them all options for each cabin.

Generally the lower you are and the more midship you are, the less you feel waves.

As stated, low and midship.  Oasis class is the most stable and you rarely feel anything.  If they are prone to sea sickness, I'd recommend them scopolamine patches.
