Crystal Palace Early ADR vs. EMH

[scrapfrenzy]

Hello! We have an ADR for Crystal Palace at 8:15am, but it's on a day where the park has an EMH opening of 8:00am. My hope was to be in the park with no crowds so I can get some solo photos of my son walking down main street as many have suggested. How early can we enter the park for our 8:15am ADR? Will I still have an opportunity for some good photo ops? -- Thanks!
