angelhair, the first time I took my granddaughter, then 6yo, it was over spring break week. I'd read the UG too, and was at Magic Kingdom by like 7:15am!lol I thought they'd open the park early for sure for spring break week before easter and all. Nope. We we the very first two in line; nobody else was there.lol But, something good did come of it. We were picked to open the park that day! It was awsome! After that my granddaughter thought she should get to do it every time we went. We've been many times since then and I've never seen the park open before it's scheduled to. Just get that extra sleep (you'll need it) and arrive about 30 minutes or so before opening.
