If you don't see it, there's nothing I can say that will illuminate you.
I wonder how flexible your company would be if we weren't in the slowest recovery from an economic meltdown this country has ever seen...
Back on topic...
As for whether or not to go to WDW while unemployed, let me tell a little story... (those who have heard it can feel free to go on about their DISing)
My company went thru multiple downsizings back in the early 2000's. My department was finally cut from 44 to 4, and I wasn't one of the 4. Fortunately, I had seen the handwriting on the wall months before, and had planted resumes across a wide spectrum of opportunities, one of which took root and sprouted, and I had already received a job offer for an opening that wasn't quite ready yet. So I took the severance package like a good little trooper, and then did the "lost job" drill -- went to the transition seminars and went out on interviews (and even got
another job offer out of those).
In essence, I wasted the time between jobs when I could have been reconnecting with my family and myself. Even working with the safety harness, I didn't dare to slide over the edge into non-productivity, even for just a few weeks. In retrospect, I should have taken the time off and driven to Yosemite with the family.
OP, only you and your DH know your true situation, whether or not you've got the cash reserves to withstand a long job search -- even whether or not DH has good prospects for a quick return to the work force. If you have the risk tolerance (and a good cash cushion), then by all means, take the vacay. It's practically already paid for.
If, on the other hand, you're not certain there's another job right around the corner, or you might have to pick up and move to where there might be a job, then I'd suggest cancelling the vacay, selling the party tix, and waiting until you're back in the land of positive cash flow to reschedule.
