Okay ... I have 3 adult and 1 kid MYW tickets through my Disney package for tomorrow. I'm thinking of upgrading to an AP. I figure our 10 day non hopper base passes will have the following value after we use them once. $1,335.51. IF AP's cost $616.31 per person for a total of $2,465.24, then my upgrade to an AP will cost $1,129.73. Can anyone with a math mind confirm this?
