I would definitely choose the gift card over the FP. I'm pretty sure this is how the Birthday FP works: You get your choice of x amount of rides from the "Donald" group and the "Daisy" group. The number of rides (x) you get to choose from each group depends on the crowd level that day; however it is kinda counter intuitive because the higher the crowds, the fewer the FPs you will be able to get. The "Donald" group includes the major rides such as Splash, Space, and Indy And the "Daisy" group includes Autopia, Buzz, Roger Rabbit and Big Thunder I think.
