Seems like a lot of DHs are like you Dan, but I thought I'd toss my two cents in as a chick who (dons flame retardant frock) doesn't really get it either. We've visited WDW several times in the past six years and have had a good time, but I don't get it being a family's sole vacation destination all the time, every time.
We visit Orlando each fall for the primary purpose of attending Halloween Horror Nights at Universal Orlando. So the attractions don't lose their lustre for us, we alternate each year between staying at Universal and at WDW and typically don't "do it all" in each place while we are there. Even so, some of the lustre has worn off some things.
Honestly, if it weren't for
HHN, we probably wouldn't even visit Orlando more than a few times a decade because there is so many other wonders our world has to offer. Some incredible non-Disney things we've done in the past several years:
-A helicopter to the bottom of the Grand Canyon? What a rush!
-Hiking the Mayan Ruins in Mexico? Fascinating!
-Winding your way through the cloud covered cliffs over the Pacific Ocean? Breathtaking!
-Everything in Las Vegas?? Viva Las Vegas!
-Standing in the midst of the Redwoods in Muir Woods? Humbling!
-Lounging on a semi-private beach with a fruity frozen drink in the Caymans? Heaven!
-Kayaking through the caves in the ocean cliffs of La Jolla? Thrilling!
-Shopping, eating, visiting museums, and seeing shows in NYC? Rockin!
You get my drift I'm sure. While I think WDW is a wonderful place with great service, lots of fun, and plenty of memories to be made, I just don't think it's the ONLY place. While we've had a good time at WDW, we've also seen, learned, and experienced so many fantastic things in each of the places that we've visited, I just couldn't imagine limiting ourselves to a theme park all the time. It's a great place, but there is so many fabulous things in the real world that people may never see if they refuse to vacation anywhere but in WDW.
