It seems WDW tickets (unused/unexpired) can be used at Disneyland. The question is, can that Disneyland pass be upgraded (either additional days or annual pass) by paying cash difference? How would they determine what was paid for the particular day used and much credit may be received? Anyone with direct experience?
