I was up and on at 6am on the dot but the dining website won't let me past my check in date! I have my reservation linked with tickets and the dining plan. It is only letting me access my check in date of 12/8. What gives?
Try it again today at 6 eastern. If you fail again, call at 7 eastern The call center cms will be able to do it for you. Don't just wait until the next day for the computer to let you.
