Richard -- as I wrote above, we've experienced no problems with vibrations being in 767, the center of the 5 aft cabins. Well, there have been some vibrations, but only because the entire ship has been rocking and rolling the past two days on our trip up to the Marquesas in swells up to 20 feet. Everyone on the crew indicates this is highly unusual. But in terms of noise from engines or vibrations under full steam, I'd say there's nothing I'd be concerned about with our aft cabin.
