Option 2 actually can cost them something, depending on how people respond. While there are some people who don't care about prices and will spend whatever to do whatever, most people have a budget or at least a set amount that they can stomach shelling out before the cost ruins the enjoyment. These park-goers are only going to spend so much. So, once they reach that amount they will modify their itinerary or eliminate some purchases. If they choose to keep an AP they may now downgrade a tier to absorb the price hike. If they stay at the same AP tier they may book a cheaper room (Disney moderate instead of Deluxe, Value instead of Moderate, pool room instead of 1 bedroom, standard view instead of garden view, etc.) or just stay off-site at a hotel/house that offers more space for the same price (giving Disney a negative profit). For those who must stay on-site they may eat at lower-cost restaurants. Instead of the Signatures they usually book, they might do some moderate ADR's, mix in some quick-service or even (dare I say it) eat at a non-Disney restaurant nearby. Perhaps they don't splurge on that dinner show (never seen so many openings for Hoop de Doo or the Spirit of Aloha shows in my life), or they limit themselves on drinks, and even ignore that souvenir they normally would have bought. (See: Banshee discount pile in Windtraders).
The point is, option 2 costs something. It just moves the loses around. The question is will there be enough increased revenue to overtake those losses significantly enough that the results aren't too flat? I don't even think Disney is that confident they will since they took the same opportunity to announce an immediate and a second, future increase in hotel parking charges.
What we will see in the short-term is exactly what Disney wants from all of this. More out of state and out of country visitors who spend spend spend. The question will be, how many more of those guests will they be able to attract than they already are getting? Because that's the only way to offset the inevitable losses on the AP side of things.
