This part was kind of confusing earlier in the thread . . .
You don't have to stay on-site to get early entry. If you purchase a 3 day or more pass, it automatically comes with one EE day. You just need to check the schedule for which days are EE days, get to the park about 90 minutes before actual opening (7:30 for a 9:00 a.m. opening day). Get in the EE line, and right at 8:00 a.m. they will start letting EE ticket holders in. Mostly Fantasyland rides are open, plus Matterhorn, Buzz, & sometimes Space Mt. You can get alot done in that first hour if you so choose.
