I joined the DDD group on fb and there is a post there talking about DDD possibly selling out on or before tomorrow! Who knows if that will actually happen, but if you are thinking about doing DDD, I'd sign up today if I were you. They have gotten a lot of registrations at the Expos. Apparently even the Disneyland half, on its own, has more registrations so far this year as compared to last year at the same time.
