I don't know your husband, but that is a common misconception. We ended up in 2007 going with my DW BFF and her youngest DD. BFF convinced her DH to come for 4 days - that's the most he was willing to stay. He hates crowds, hates waiting in line...his idea of a vacation is going off into the woods and shooting at animals. Even BFF wasn't really into the idea of going, was more going for her DD. (Older DD goes with friends every year, younger DD never went.)
Well, they had an absolutely great time. It helps that with me, you never ever wait in line for a ride. We went end of September, so the crowds were atrocious, but were definitely there, but we had to contend with the heat and rain...and still they loved it. Now, they really aren't in any hurry to go back again, but they did really enjoy themselves.
Personally, I don't know how someone that has a clue as to what there going into at WDW wouldn't have a good time, no matter your personality, you can tailor the vacation to them. With you already having been there, and you knowing your DH, I don't think there's anyway he doesn't have fun.
Too bad you have to wait until 2012. I think we'd have a tough time going 2 years now that we are full-formed Mousejunkies. We have a big trip planned for 2012 that likely will prevent a WDW trip that year...so we are already thinking a 2011 trip is a must. (I don't think 3 years between trips is doable for us anymore.)
And yes, WDW is expensive...but it can be done on a reasonable budget. Our family skis, and a budget Disney trip is much easier to pull off than a budget ski trip. One of the reasons we keep our trips low budget is so we can go more often. We've spent under $3000 (including air fare) on each of our trips to date. We only spent $1300 this past trip (not counting our AP tickets, which were already paid for) for 5 nights. Yeah, we skipped the
DDP and avoided TS restaurants, but we still had a great time.
