I've been way forward on Grand Class ships (201 on Lido) and unless there are really heavy seas, with this large a ship, you don't feel much of anything. Baja is a good deck in that you have cabin decks above and below you, so less impact from noise from public areas of any kind - ie the above mentioned Lido deck "cabin from hell" was under the treadmills and weight machines in the gym. Have also had cabins over the theater, the anchor chain, and other interesting locations. I prefer cabins on decks surrounded by other cabins. Should be fine.
