I have a day pass to hike in early July. I don't want to start super early and was planning to begin around 5am or so.

1) Given the construction issues, do I need to worry about finding a parking spot in the day lot this late? If for some reason there was no spot in the day lot, what would my options be?

2) I understand that the day lot parking pass is good starting at 12:01am. Would I have any issues parking up there the night before (like at 9pm and sleeping in my car)?

Thanks
