Disney used to market like this:
Old commercial 1
Old commercial 2
Old commercial 3
Now, here's a challenge ... find me a WDW commercial produced in the last 5 years that isn't at least primarily focused on two parents bringing their two kids (ages 5 to 8) to the Magic Kingdom.
Generally, the mother is shown in the commercial to be the one who pressed the issue (she discovered it was affordable, or she suggested the trip, or she's the one telling the kids to go to bed so they can go on the trip the next day). The husband will be enthusiastic, but has the "never would have realized it, unless you told me" attitude. 90% of the time, the little girl will be in a princess dress and the commercial will end with one of the kids hugging (or holding hands with) one of the characters.
After a quick search, here's four examples:
New commercial 1
New commercial 2
New commercial 3
New commercial 4 - this one's not even for WDW, it's for batteries, but it's still a Disney commercial
Now, maybe they've got a range of commercials showing elsewhere that I'm not seeing, but all I know is their marketing for the last 10-15 years has taken a dramatic shift away from "Fun for Everyone - look at all the varieties of things to do" to "Moms, you're screwing your kids if they don't get to go to Disney and hug Mickey or a Princess". If you don't have little kids, Disney isn't even close to interested in convincing you to come.
EDIT: In the interests of complete transparency and historical accuracy, the earliest example of what has become the model for their modern marketing was from a commercial right after WDW opened (and has to be the single most shameless commercial I've ever seen - I can't believe I found it on YouTube):
Saddest commercial ever
