Frankly, I think the Passporter, et al, do travelers a dis-service by tagging rooms as noisey or undesirable thus causing what typically amounts to unnecessary anxiety. I stayed in a 2518 on my last cruise, supposedly noisey due to being under Diversions, and I heard nary a peep from above. A little girl next door was all I heard.
There probably are some noise issues with some rooms, but I think these lists are made by looking at a ship's map and not from good research or experience, and I'd personally prefer to have no information than bad or false information.

PS For the record, I chose to be under Diversions for my next cruise vs mid-ship as I liked being far forward. The first time I was there, it was because my room was a GTY and not by choice. This time, it's by choice.
