DH will go, but only if we're already in FL for another reason, and there is spotty participation even then! Works out to maybe every 3 years, but WDW with him is a very, very different type of trip than when I am solo - he requires a lot of down time away from people, which is not always easy at WDW. I have to plan, plan, plan, line up the best rides and then get us out of the park.
For a few years, I was just doing solo single days here and there before meeting my sister there (she lives a few hours away from WDW, and I'm on the West Coast so always come in a day earlier than she does). However, last year, I was concerned about flight cancellations with a hurricane brewing and extended my trip to fly in 3 days before meeting her. I figured I would be there to help her, at least, if needed. The hurricane went elsewhere, and those 3 solo days were aaaaahmazing. It changed my whole outlook about being there alone! I have already done 2 full solo trips this year and am doing 2-3 days solo before meeting her next month. DH thinks I'm a little nuts, but our incomes and finances are separate, and he does trips alone to visit his mom twice a year, so we just coordinate around each other. I adore him, but honestly, Disney is lots more relaxed without him

. It would be great if he liked it more, but I like having that time to myself!
@georgina, be happy you're not a diver! DH and I are both avid divers, both at home and abroad, we do two big trips together per year; the combination of cold water dive gear for home, trips to the Indopacific, and my Disney problem, and well, let's just say I look for opportunities to be cheap in other parts of my life!!
