On the Disney website, does it say anywhere specifically when you are paid in full? I booked through Costco and the balance there says $0 now that I have paid it up (whoo hoo!!!!). But when I go on the Disney website it says that my booking window opens up on such and such date and that "when I have paid in full" I can book activities. I am just a little nervous that Disney doesn't think I have paid in full. Or is that just the standard line? Thanks all!
