question about the fun card

[Disneynutbsv]

Hi!! I have the funcard passport. It says on the website that if I buy tickets to get into the park (this is for a friend), I can get a discount on the tickets. Does anyone know how much of a discount???
Also...one more question, if you had your choice of going on Thursday, Friday, or Tuesday, what day would you go to Sea World?
Thanks for the help!
