Couldn't the tickets be bought with the FD package and then picked up early? That is what I have been told. We have FD in August on a BB offer which couldn't start until the 20th. We have 8 day hoppers on that package with only 5 days in our resort on that package, then will arrive earlier (on the 15th) and pick up the tickets as early as allowed. Right now we're planning a resort day and water park day, then picking up the tickets 3 days early. But I have also been told, on these boards by someone who works in ticketing, that with the MB we might actually be able to activate our tickets as soon as we get there on the 15th and then add park days to our 8 day tickets if we want more.
