We didn't wait 3 hrs for Paint the Night in 2015, and our spots were just fine. There wasn't a nighttime parade on our last trip, but we also had no issues finding a good spot for the Christmas Fantasy parade in Town Square in the afternoon...we pretty much walked in to main street as the parade was starting back at small world, and we found a good spot right in town square pretty easily. This was (IIRC) a Friday afternoon (of a runDisney weekend). We were in the parks on Sunday afternoon on both trips (2015/2016) and didn't feel it was much different than the rest of the weekend (obviously there was a big difference between Wed/Thurs and Sat/Sun, but that was expected). Both years we were there on the opening weekend of the holiday season (w/runDisney events). It was definitely crowded, but not so terribly that it was pointless to be in the park.
We had no issues with F! back in 2009/2010/2011 (and definitely didn't wait hours for it either), but we did appreciate having the dinner package in 2015 since we had a stroller with us then (DD's first trip).
Maybe we're the exception, I'll grant that. I do know that lining up for parades has been an issue...it's just not been one that's affected us personally.
