Ok, I bought 1 day tix with our package, thinking we would use our no exp fom last year, but now I think I want to save those and upgrade our 1 days, however, I'm trying to do the math and I don't know if I should take the # of days that I want (6 day base) and subtract the old 1 day amount because we bought before the increase, or subtract the new 1 day ticket amount...and the difference would be what I have to pay...I think, anyone know??
