An AP most definitely saves. If an AP goes more than a certain number of times, the pass pays for itself. You see, when a day ticket is 100 dollars and an AP is 500, once you go six times, you've gotten into Disneyland for free (I know those aren't the real prices but it's simple enough math to prove my point).
Of course, that doesn't include the discounts they get on food and merchandise.
Now, my argument, in fact, is not about taking anything away from the APs. It's that when the AP's visit costs less, and is worth less due to the repeatability factor, why should they get an extra perk of more time in the park over the tourist? I'm not saying that the AP's benefits should be taken away in favor of the tourists, but why exactly was the decision made to give, of all people, APs more time to play? Especially when you consider tourists are paying more per day, eating in the park, buying souvenirs (all for full price) and possibly staying in ridiculously expensive hotels.
As for what you said about the tourist only getting to do what their time allows--that's exactly my point! So thank you for proving it for me the tourists are on time crunches, regardless of their financial situation. Seeing it all as many times as an AP does requires extra time in the parks, which makes it seem strange to me that extra hours would be offered to APs who can and probably have seen everything hundreds of times already.
