This was on a Tuesday during the second week of December, a period that used to be a slow time of year but is now clogged with Disney fan meets,
D23 events, etc. Crowd levels were moderate that day, but Candlelight Processional was packed.
Mind you, I wanted a seat toward the front of the reserved section, so if you don't care, maybe you don't have to arrive as early. What stressed me out was that the line was all the way down to Japan when we arrived an hour before the time we were scheduled to be let in. We ended up getting seats that were off-center but still in the section of the dinner-package area closest to the stage.
You can see pictures of our view, our spot in line, etc. in my trip report,
