Momentary Devil's Advocate:
If you are going to the Park on the 17th at or near Park Opening (which has now been moved to 7am) and will not be able to leave the Park that day for fear of not getting back in ... you would have to be out of your room at the same time as you leave for the Park at the literal crack of dawn.
The Angel on Your Other Shoulder Says:
But it will be so much easier to get to the Park at the literal crack o' dawn if you are staying on-property.
