DH (50) and I (40) are childfree and have just made an offer on a DVC resale - I already have the vacations through 2005 planned out! While DH does love Disney, I have definitely made him addicted since we've been together. (I first visited in 2nd grade the spring after WDW opened - stayed at the CR with my Mom and Grandma.)
We do, however, have 8 dogs and 2 cats. A realtor once asked me if I had kids and I said yes, eight (I'm really a dog person and always leave out the cats) but they all have four legs. She just stared at me and said "Eight kids and they're all mutants!". Had she had the right house, she would have made the sale right then.
And to those wondering - my mother-the-saint comes to our house and lives in while we're gone. I love my Mom!
