You know, I was just talking about this with someone else.
My wife and I have no kids yet, we have been married a year and a half, in our late 20s early 30s. We honeymooned at Disney last February, and already our friends asked us ... "really ?".
They kind of blew it off as something cute, for a honeymoon they could kind of understand, but they still thought it was weird. "Don't you want to go down south ? Sit on a Beach ? Drink all day ? What about Europe ???" etc etc ...
We came back totally in love with disney, greatest 8 days of my life I think. And of course, couldn't wait to go back again. Sometime in the fall/early winter, people began planning trips for the winter (we live in Canada, we all try to get away for a bit if we can). A group of friends wanted us all to do Aruba, another Friend was booking Punta Cana and wanted us to come, Anothe group wanted to do Sandals, another couple were going somewhere else down south. We, wanted to do Disney again, even bigger and better than the last time, and we would have loved to share it with some of our 'young adult' friends...
The amount of crap we have gotten from our friends about "maybe we we have kids we will do disney" and "isn't that just a little kiddie?" or "Isn't there somewhere better you want to go, like an all inclusive beach resort ..." etc etc etc ....
Its so difficult to explain to people just how awesome disney is, how much there is to experience, how much you can do and at the same time how relaxing it all can be. How fully entertained you are ... its just awesome.
Its funny, our friends come back from their all inclusives, and they have a bunch of pictures, but not too many, and all they have really done is sat on the beach, drank, swam, and went out for dinner. After a while the pictures all just look the same. I am sure they all love it, and I am glad that it works for them.
My wife is working on her scrapbook (its her hobby), she is on Day 2 of our 8 day trip. I can tell you she has more pictures, and we had apparently done more in the first 2 days of our trip then our friends did on an entire week of their various beach resort vacations.
Disney is awesome. But it seems really hard to make people understand. I know I didn't, until I experienced it. One of the major reasons we booked it is because my wife is a huge Little Mermaid fan (Her grotto was closed while they were building FL2

) and because they offered
free dining ... couldn't pass it up. So glad we didn't.
