Deck 1 is probably the <i>best</i> place to be in terms of not feeling motion. It's pretty close to the Center of Gravity, meaning that if the ship rocks, it will pivot around a point near your room... so you won't feel so much motion. As far as convenience... you're near the Midships elevators. You'll probably take the elevators everywhere except perhaps Deck 3. But you won't have any problems with crowds getting on the elevators because there are only a few staterooms on Deck 1 and it's at the "end of the line".
Do you have a stateroom #? 1030 - 1037 is in a somewhat noisy area, but the rest of the staterooms on Deck 1 are quite quiet.
