If you go to "View Cruise Details" under the number of days left, it will show you whether you have main or early dining. I think that you have to wait until you are paid in full before you can see the link ressies.
Oops, I think that I may have been talking about something other than what you are referring to. If you are talking about you dining rotations, you won't find that out until you receive your KTTW cards boarding the ship.
