No alarm clocks. No wake up calls (unless you want to hear Mickey). No prodding the other sleepy family members.
In the park, no prodding of the little'uns to get them to move along. If one straggles, you should slow down and say nothing until he catches up. (You may prod them to indicate which way to go.)
Yes, if you rise early get into and out of the bathroom right away so it will be empty for the later risers when they get up.
Yes, if you rise early, get things ready including the coffee if you want to speed things up.
Yes, let some of the family members leave for the parks earlier than others if they wish. And those not wishing to return to the resort for a siesta can stay in the park depending on how hot they feel.
Yes, let it dawn on the late risers all by themselves that when they couldn't see and ride everything because they reported to the park late, they will get up earlier tomorrow all by themselves.

Some gift shops have two entrances. Be sure your rendezvous points are unambiguous.
