Chiming in as a married Disney fanatic. DH isn't into Disney. I can get him there maybe once a year for F&W, and maybe once to
Disneyland for a quick visit. He was raised in Europe in the 60s so he didn't have the Disney childhood I had. But he's fine with me going solo, so that's what I do. I have done Tokyo and Paris on my own as well, and boy were those tough as a solo. Nobody wants to talk to you! Normally, I make temporary friends in queues, or at a restaurant or bar, chatting about our trips, imparting tips, etc. Not overseas! Everyone is so afraid of airing their (to them) poor English.
I joke to DH that if he dies first, I am going to get me a Disney-lovin' second husband, because his (my current husband's) Disney-apathy is his only flaw.
