I went last Sunday, crowds were better then 2 Saturdays ago.
Nemo line would usually line up all the way past the cave that the subs go in, this time around, it was at where the subs make their first turn. Less congested as well, not a major difference, but noticeable. Overall, it was nice. Even over at DCA, lines weren't too bad. Of course Toy Story Mania got a lot of the attention, but the wait goes by fast. It's almost as you were constantly moving through the line.
Hope that gives some light for this upcoming Sunday.
