5. Well-Rested Family
Fellow parents, you'll appreciate this one way more than those visiting without kids. When you arrive at Magic Kingdom in the morning, you'll probably find that your little ones are on their best behavior at this time of day, due to being in their most well-rested state.
Perhaps there will be some afternoon grumps later on, but for now, enjoy this peaceful family experience while everyone in the family is in the best mood they can be in.
