My DH is a big Disney fan. He didn't start out that way. His first visit was for our honeymoon. (I went lots of times as a kid.) He wasn't exactly feeling the magic on that trip. I threatened to have the marriage annulled if he didn't hurry up and get in the Disney spirit. Well, it took a few more trips, but sometime during our 2004 trip, he finally got bitten by the Disney bug. He's the one who talked me into the trip last year and this year, and told me he now wants to make at least one Disney trip every year. (I'd like to take a cruise sometime, maybe a
DCL cruise and a shorter trip to the World in 2008.)
Grumpy pajamas are now his preferred lounge wear. When he hears some futuristic music, he'll say how it reminds him of Tomorrowland or Future World. He always wants to visit the
Disney Store when we're at the mall, and we saw Ratatouille this past weekend. (We don't have children. We're having too much fun being kids ourselves.)
So yes, they are out there, or you may have to convert one. I think once you find someone who might be the one, you should take them on a Disney trip before making a long term commitment. I wouldn't want to spend the rest of my life with someone who didn't "get it". If he's not into Disney the way you are, you probably would be incompatible in other areas, too.
Best of luck in your search for your Disney soulmate!
