So funny that you posted this.
I'm not Disney'd out yet, but I have to admit that I'm not quite as excited for this trip as I have been about others. I think the biggest factor is that my DH is, without a doubt, Disney'd out.
We've gone many times over the last four years. We don't live close, so it always involves a flight, and our stays range from 7-10 days. I do all of the planning, but have involved the kids more now that they're older (DS9 and DD7) and can tell me about which rides/characters/ADRs are must-do. But DH is just done, and I get it. Last year was supposed to be our last trip, at least for a while, but then I started getting wistful about the kids getting older. I asked him if he could do one more trip, while DD7 still really believed in the magic, and he surprised me by saying he'd go again. He's still not excited about it, but I think going for the rest of us. And as happy as I am to be going again, I feel badly for him and sometimes wish he'd just said he didn't want to go. I want everyone to have a great time.
So... this most likely will be our last trip, as a whole family. I'll be back in February for the Princess Half, but that'll just be me and one of my best friends. DD7 tells me she still loves Disney and will always want to go, but DS9 love for the magic is starting to fade. I know DD7 would be up for a girls' trip, but we're a pretty closeknit family and I don't know how I'd feel going without DS9 and DH.
So yes... although I doubt I will ever be Disney'd out myself, I think that Disney has run its course with DH, with DS9 soon to follow.
