I really don't think that the motion in front of the ship is that much, unless the ship goes through some very rough seas or a big storm. This past summer, on the conquest, I was on the lido deck up front, about 5 rooms from the front. Didn't feel any motion. However, when four of us were on the aft of thel ido deck, we were a little surprised to feel some vibrations (not motion) from the ship.
Like a few good people suggested, take along some motion sickness medication just in case.
ps my wife had always been afraid of motion sickness, but she has never gotten it yet, even on the smaller boats like the Celebration and Holiday--and even on commodore in the gulf during a tropical depression.
keep thinking fun, fun, sun, food, music, food, wind, pretty things to look at, food, etc, etc,
