I know that we have been thinking that there would be no exclusive AP previews for TSL due to how much construction is needing to be done still. I think this basically confirms that there will not be any AP previews. So, since Disney didn't offer those to AP's, they decided to give them exclusive access after the "summer rush."
This is also something that I wish they did with Pandora. I specifically remember going into the AK Guest Relations building last year to give a cast compliment, and there were many AP holders in there just complaining to CM's that they couldn't get any fastpasses for any of the attractions (mostly FOP), and they were not going to wait 4 hours to ride the attraction. Obviously the CM's couldn't do anything, but that really got me thinking about
MDE, and the exclusive access to fastpasses that they give to people staying on property.
Honestly, I really think it would be so much better if WDW adopted the Maxpass system. It would be nice if Disney didn't charge for it at WDW. I only say that, because it gives a fair chance to EVERYONE entering their theme parks the equal opportunity to get a fastpass for TSL, Pandora, or any attraction in a theme park that people are going to that specific day.
