We are planning on being there for the not yet announced 24 hour party on May 22nd. After using the first 3 fastpasses, I know we can keep getting more one at a time, but I remember there being something about being in the same park. Our plan is to hit all 4 parks and I am curious about if I pick the first 3 fastpasses for animal kingdom, can I then switch to another park and make the single fast pass selection there? Hope that makes sense.
