We've stayed Deck 5 aft on the Wonder before. Going through our cruise history we've been in 5638, 5646, and 5520 (this is forward, but about the same distance from the center of the ship). Personally, its my favorite area to stay. I don't get bothered by motion at all so I don't really notice it. I guess we've felt the thrusters but no more than I can remember on the other ships in other staterooms. The part I like about deck 5 aft is its almost "hidden" back there and very quiet. Its a short jump down the stairs to the aft restaurants as well as having navigator's verandah's (our favorite room type). It looks like there is a bunch of us on deck 5 aft this cruise. Looking forward to seeing everyone! Clint 5632
