If you purchase Express Passes, does a child under 3 need one, too? We stayed onsite when we went and she had her own hotel card FOTL pass. When we all rode, we showed and they scanned all 4 cards. If we decide to stay offsite and instead purchase the actual Express Pass, does she need one or is she good since she's under 3 and won't require a park ticket? 
Thanks!

Thanks!
