Question about fast pass and child swap - I've never done child swap before. Right now I have 3 fast passes for FOP - me, DH and DD8. DD4 isn't tall enough. Can I change my fastpass for Navi so I can ride with her while DH and DD8 are on FOP and then use the child swap feature to ride FOP afterwards on my own? Or will I have to show that I have a fast pass also to do child swap for that ride? I don't want to risk not being able to ride FOP, but would otherwise try to ride navi with DD4 during the time DH and DD8 are on FOP so she's not just waiting around for them and then me to be done.
