I must appologize:
ChatKat were on the Navigator, not the Voyager. We have been on the Navigator twice, midships and toward the bow. We had no problems there, except for the show lounge where the screw noise/vibration made the lecture difficult to hear.
Because of this, we personally will book suites on the Navigator midship and forward --- unless and until a "fix" for the vibration problem near the stern of that ship is confirmed.
And the same goes for the Voyager.
Thanks,
Richard :) :) :)
