Weget up when The Boss (my DW) tells us to. She is an early riser, but the rest of us aren't. We still make it to the parks usually just after open.
We get up at about 5 am at home. Sleeping till 6:30 and getting there for rope drop is sleeping late! We always make rope drop.
My dd and Dh are early risers (5am) everyday winter or summer regardless of what time they went to bed.So we are up and at em for rope drop.
