I was just checking to see if my waitlist miraculously came through (it did not ) and I see the the link now. It is right there when you click on "Vacation Details". I am debating if I will do this or not....we arrive at 9:00PM so I don't think there should be a wait to check in. I have not paid much attention to the threads regarding online check in so I am not sure what the advantages are if any.
