Does parking at the "good" spots get so filled up that you have to go stake out a spot an hour before sunset? Ditto for the sunrise spots, although we'll be up very early and out and about for the day.
Sunset is at 7 when we'll be there, we would love to go have dinner and a beer around 5 or 6, then head back into the park until closing time at 8:30. Is there a rush hour at the restaurants after sunset as everyone gets back to the resort in droves? We've been at scenic places in the US where this happens.
A sandwich in the car along with a beer as the sun sets might be very enjoyable, but I think I've read that alcohol in the park is illegal? (feel like a lush for asking this!)
