I feel your pain. My husband is the exact same way. He strongly dislikes going to WDW. Now if WDW had a park with actual fun and exciting roller coasters, he would reconsider. But since WDW is a family park with no such rides, I won't be able to convince him.
He has "suffered" through 3 trips to WDW and a
Disney Cruise the last 10 years and he is done. So now I am having to go to other destinations. But I discovered that when we go to New York, there is an awesome
Disney Store. And if we go to Europe, there is
Disneyland Paris.
I know it sucks not being able to go to WDW for every vacation, but maybe if you go to a destination that she wants to go, then maybe next time she will reconsider and go to WDW. But if not, then I guess you and the kids go to WDW and try to enjoy it, even if she isn't there. My husband dislikes Disney, so when I had a chance to go to Disneyland without him, I went. It wasn't has much fun without him, but then again, I didn't constantly hear how much he hated being there and I enjoyed Disneyland.
Good luck with your next vacation, where ever it may be.
