It's not that he doesn't like it- he loves it. I guess it's more financial. We don't have a ton of extra money, but I've carefully saved for our last two trips, and we were able to do them without sacrificing in other areas, and without having to put anything on a credit card (I'm not comfortable doing a trip that puts us in any debt). I did use a chunk of our tax return though, combined with my vacation fund savings. He also doesn't want to be "stuck" going to WDW for every vacation.
I think we just have very different styles of picking what's important to us. I read an interesting article recently about different styles of "spending for pleasure". The article was written from the perspective of someone more like me- I'd much rather spend a big chunk of money on something that makes memories- like a trip to WDW, rather than "stuff". Dh would rather spend money on stuff he can have & use on an ongoing basis. For example, if we have X-number of dollars we could spend on a WDW vacation, he'd rather use that X-number of dollars (at least this year, anyway, maybe not always) on things spread throughout the year, like HBO, a cool new TV, and iphones/upgraded data plans. I'd much rather forgo all that stuff for the one big trip.
My sister is currently in WDW for two weeks, with her family of 6. We've already talked about maybe doing a sister's quick-trip (we could each only get away from our respective families for a couple of days, tops). She's loving it, but there's so much more she could do and/or enjoy in a different way if it were just us! And maybe dh will get jealous enough to see the error of his ways
