I've been thinking about this and at first glance, it seems unfair but after further thought, I'm not sure it really matters. Say Disney opened the park early before official posted time but still waited until the posted opening to start excepting boarding groups, the people already in the park are still going to get the boarding groups first while the 7am folks are still trying to get in. It's the same result. Say Disney decides to not open until the posted 7am, the people that get there super early will still be there waiting in the front of line which will result in them getting in first and still getting the boarding groups first again. It's still the same result. Bottom line, if u want to be guaranteed a boarding group number then get there early cause no matter how Disney does it, the end result will always be the same and that's the early bird definitely gets the worm in this scenario. That said, I plan on being at the park around 6am on Friday the 20th and will be shooting for a late afternoon BG.
