Can I get use my FP card to get a FP for Space Mountain, for example, then give that FP to one of my older kids and then go and get another FP for Philharmagic for example? I guess my question is can I, theoretically, go and get all my FPs for the day and hang on to them until later or do I have to use them as I go? I'm planning on giving some of mine to the older kids (along with my FP from my ticket) since I'm going to be sitting out a lot of the FP rides.
