Hello everyone, DH and I stayed in an AFT balcony suite this past January. Yes there were vibrations and noise until we got close to Roatan. I had previously read where someone had stated the vibrations and noise was due to high speed. I'm thinking that may be true. I believe we left on a Saturday evening, we had vibrations and noise Saturday evening, and all day Sunday. When we had gotten up on Monday morning it had stopped. Of course Monday Morning when we got up, we were really close to Roatan. After Roatan there was no more of the vibrations and noise.
A couple of things I did. In the bedroom doorway to the bath room was a vent which rattled alot. I threw my make up bag on it. That helped. In the living room a towel was put under the plant. (it rattled against the glass table). I put something infront of the closest door to keep it somewhat still. It would crack open and a light would come one.
At any rate, the noise and vibrations lasted appx 36 to 40 hours. When it stopped we thoroughly enjoyed the Aft facing balcony suite.
