I am unsure whether will go to US/IOA for 3 days or 4 days. If I buy a 3-day pass and then decide I want a 4th day, can I convert the 3-day to a 4-day ticket? Would I just pay the difference, or would it cost more than if I had bought the 4-day in the first place?
Same if convert from single park to park-to-park after purchasing - does it cost more than buying park-to-park to begin with?
