Rode it last month. Looked the same as always to me. But, that could mean that it has always been dusty!!! I don't think it's bright enough in there to really notice.
We rode in on Saturday and it was wonderful...however, we hadn't been on it since 1991 (!) and were so busy watching our girls experience the magic, we might have missed the dust.
My issue with PP is the ride over the town, which has always been my favorite part. It used to be dark except for the MANY lights from the buildings. Now there isn't much of the town left, and you can see big white spots on the floor where there used to be buildings.
Don't get me wrong. The ride was great and was a family favorite. I'm not saying it was a little dusty and being nit-picking. I mean huge clumps of dustballs (in the water most noticeably).
