Rest and a sleep in day.
It is important not to wear your self completely out, you won’t have fun if you do.
I recommend having 3 early mornings before having a sleep in day. A sleep in day is not an alarm or a park plan. It is for resting and recovery (also getting ready to go another day).
It is a good day for hanging at your resort, swimming, relaxing, going to Disney Springs or maybe checking out another resort.
After all, it is a vacation so it is meant to be fun AND it is meant to be reastful.
Enjoy!!
