edpdiver, My wife and I were thinking about booking one of the south Komodo trips for next year. For the dates we want the upper deck cabins are unavailable. Did you hear any complaints about engine and generator noise for those in cabins 5 and 6?
Reuben,
I cannot answer the question directly. I do know that one couple who were directly adjacent to the engine on the lower deck were bothered by engine noise, but they were a little sensitive to issues I considered minor. So they may have just been sensitive; I cannot say for sure. I know that no one else was bothered at all. I hope that this helps a little. I really liked the boat and crew a lot. I would ask them directly about your concerns, and see what they say.
Best of luck.
Erwin
