My husband was layed off in July and so we changed our plans to go in August instead of wating for our December trip as he may not have vacation at that time if he's found a job. We usually give our kids $5.00 a day spending money but told them we wouldn't be doing that this time. Insead of paying $2.00 a soda at resterants we ordered water. We cut out all those extra snacks and between meal treats and brought our own from home. We had a great time and I'm glad we were able to follow through. We are DVC members and got very lucky to be able to change reservations and we have season passes so our main cost was food and souviners. I agree with the idea that we only have our children for a short time, and memories and family time are very improtant. Since you have already paid for your trip you have been fincalilly respopnsible in your planning. Your husband may not have much time off later on, Disney may not have the great hotel deals they currently have. PS. We did bring our laptop and my DH did surf the internet (monster.com) a little each day when we went back to our rooms for afternoon naps, so he was still able to get out his resume. You husband will qualify for unemployment.

MHO is that you know in your heart what is best for your family. If your hubby can draw unemployment, if you are him are likely to get a job sooner rather than later, then I would say go for it.. especially if the plans you have already made are not refundable. If you have funds in the bank to get your family through for a couple of months, then I say go for it in that situation too. Its true.. after a new job there probably wont be time off work for awhile.
When my oldest was a toddler DH and myself were unemployed for six months. What I remember about that time was eating a lot of vegetable soup (I hate it now!) and spending hours with the two of them reading and taking long walks. It was a hard time... but also a special time that brought us closer.
