That's exactly it. Sundays are a big AP day, especially when the weather is nice. But, one thing that Disney doesn't seem to take into consideration is that the Sunday AP crowd is not coming into the parks to spend the whole day going on rides like the vacation crowd does.
Disney was trying to figure out an issue to the AP solution about 4 or 5 years ago. Their problem was that attendance was down, and it was mostly AP's coming into the parks. But AP's don't spend money like tourists do. There were rumors swirling at one point that they wanted to be able to do away with AP's completely.
The SoCal/SoCal Select AP's are all but useless because there are so many blockout dates. And the Deluxe and Premium have gone up so much that most people won't buy them anymore. My first Premium pass was $189. Now they're $649. Like I said before, we are the only ones out of all of our friends who still have AP's. A few years ago, everyone that we knew had AP's. Now, nobody does. We most likely won't renew, because they're cost prohibitive, and every other park in the area has much more reasonable season passes.
I think that Disney got themselves in deep with the AP's, and is now trying to make them less desirable because they're not cost effective.
Although if this where true why the big push for AP's? With the elimination of more then six day tickets the consistent reply from Disney is to purchase an annual pass. Plus when you drive in on the tram they push them as a value. If they where trying to do away with them or get less people to buy them seems like they would tone down on advertising them.
I don't think that Disney doesn't want APs. That really wouldn't make any business sense considering their market, and as has been pointed out already, is contra-indicated by their continued heavy marketing of APs. I agree though that they might like to maintain a certain balance between the number of lesser spending park guests and bigger spending guests who use the park, and one way of doing this is obviously with the AP price increases (although ticketing prices have gone up across the board and that's just an indication that Disney believes the market can bear it, a theory so far being born out). Another change to their AP marketing has been the offer of payment plans to all California residents rather than just locals. This increases their numbers of APs and their income from AP tickets themselves while not severely inundating the parks with more guests on a day-by-day or weekend-by-weekend basis since these further away AP holders are actually vacationers rather than day-trippers. This also creates a heavier spending subset of the AP population to balance out the supposedly smaller spending base of local AP holders since out-of-towners will be more likely to spend more on lodging, food, and extras than those locals that have an AP or regular tickets.
As far as whether an AP is a good value, that's an individual choice and completely relative to individual circumstances such as income, location, other hobbies, interests, vacation wishes, and so on. Our family doesn't live in SoCal, but we choose to spend most of our entertainment and vacation money on going to
Disneyland three to six times a year for multiple days at a time. The AP therefore is a good value for the amount of entertainment we get from it. On our last set of APs we entered the parks on 28 separate days for at least two hours each time and anywhere from eight to eleven hours on most days. For the old AP price of $499 for a premium, that averaged out to $17.82 per day, and at the current AP price of $649, that average goes to $23.18 per day which we still found reasonable. A local who might more easily visit the park for the same number of days a year would be paying the same average cost or less if that person is willing to work around block out dates and choose a lesser priced AP option. Plus, the local has more options and control over extra spending on lodging, food, and stuff than someone coming from further away. So in comparing these prices to the costs of movies, ball games, theater, gym memberships, and other forms of entertainment, the pricing isn't all that unreasonable. When and if AP prices get too expensive for our budget, then I guess we'll go back to what we did before we could afford them, and that was go once a year with tickets or not go at all and find other interests and activities with what money we have.
