I travel to both WDW and DL each year. For the most part, I prefer the AP guests at DL resort. They are less frantic, and intent on getting their $$ worth out of each day. I see more parents going overboard at WDW, where the parents are thinking about all the $$ they are spending, and where is often unbearably hot (8 months out of the year!) At DL, the locals generally don't care about always getting characters autographs, for example, which means character meet and greet lines move faster, and are often shorter. The characters are even free to walk around, greet people, interact, often without handlers. I have seen them take one child by the hand, and walk over to a bench or wall and have a private conversation. And great adult interaction, too. I love that.
Yes, the frequent DL guests DO tend to chant the spiels along with the rides, but that is not THAT bad. I would rather guests sing along on Pirates, then talk about their last Drs visit to the person next to them, loudly. And guests there also DO tend to mug on the ride photos, but I think that is funny, too. The DL locals tend to bring in their food, carried in large backpacks, which can be annoying when they turn suddenly and whack me in the face with it, in a crowd. But it means lines in many of the food venues are shorter, and you can even walk in and get a table at some full service places. I'll take that trade off.
As for the other stuff, we sort of forced our kids on some rides, and generally it worked out for the best. But, not to the point of huge tantrums. And we always took breaks in the afternoon. Lastly, I push my adult son in a WC that is like a stroller. The problems go both ways, because people dart and cut in front of us, with little chance for me to stop in time. And I am being attentive. They also stop suddenly, and if I was just a pedestrian, that would be a gentle bump from me, maybe. But my son's WC may bump you and hurt. Sorry! But its a crowd, all moving at the same pace, and you just stopped; you need to pull over to the side of the path, or glance behind you first.
It is nice to wake up at DL and say, which park will I visit today? I love not making all my plans 60 days out.
