Though keep in mind for weekends only (12/13th, 19/20th), from 11am - 8. Free entry, no reservations needed as far as I can tell, but they do say limited entry, so a line to get in is possible.
Though I do believe that I heard that since the food closing, even Downtown Disney/DCA was pretty dead... can anyone verify that? I know Citywalk has basically been a ghost town since the food and outdoor dining closures.
