The cabins on Panaroma deck should be quiet from decks above and below. You MAY experience some motion due to the location of your cabins being located forward and on a high deck. One deck down, is lido, with pools and buffet, and forward elevator is very convenient to the theater.
What information are you looking for about this deck?
I have previously cruised on the Sensation and was at the very back of the ship and did not have very much motion. I have heard that being in the front of the ship has a lot of motion and just wondered if anyone has stayed on that part of the Conquest and had any problems. We all stay on the water a lot and do not have any motion sickness.
I have had cabins on high decks and very close to the bow on other ships, but not specifically on the Conquest. IMO, if you are not prone to seasickness, I wouldn't worry about it. From the deck plans, it looks like you will have access to a public deck directly on the bow of the ship, make sure to check it out!
