I love LOVE love LLOOVVEE theme parks at night. Especially Disneyland and the Magic Kingdom. If I could I'd sleep during the day and get up before sunset then rush over to the park. I'd get there in plenty of time to catch all the lights start lighting up in my favorite street, Main Street.
And as the night goes on I'd get to enjoy the park under a starry sky. Maybe catch a visual of a shooting star while riding Dumbo.
The best thing about the overnight experience at Disneyland would be being able to see the park change from night to day, a visual sunrise experience.
Anyone else wishin' Disneyland would stay open overnight 1 night of the year? A special hard ticket event!
