Both seem to have the same hours (DL: 8 am to 6 pm, and DCA: 8 am to 8 pm) with the same entertainment, so in that way, they're pretty much equivalent. I don't know that there is really going to be a huge difference in terms of crowds on a Monday or a Wednesday. If you wait until the 30th to go to the party, there will be more chances for the folks that go to the first two to report back.
