We live close enought to WDW (we live in Atlanta) that we can go 3-5 times a year by driving. While that might seem to take away the specialness of a trip to WDW for a lot of people, it doesn't for us: every trip is as if it is the first trip in years! Anyway, three days before our trip last June, my entire division was eliminated and I, and the eight men who worked for me, lost our jobs.
My wife and I didn't hesitate to tell our then 5 & 8 year old what had happened and that we would have to curb our spending, but we went for our nine day trip to the Animal Kingdom anyway. We had a wonderful trip and it released the tension and stress the two of us were under. I think it releaved the stress the boys were under, too. We even renewed our Anual passes while on that trip.
Fortunately our insurance is through my wife and she has a good job. It took me 9-1/2 months to find another job, but I found a job I truely enjoy; one that I thank God for every day; one that pays a good bit more than the one I lost; one that has WAY less stress than the old one. It will take a while for our finances to recover because my unemployment covered my $764/auto payment and that was about all, but we don't have a lot of monthly expenses and we watched our expenses and what we took out of savings each month while I was unemployed.
My biggest piece of advise is to take your situation, however it plays out, to God. He is in charge and he will listen to your prayers and answer them in accordance to His will and His timing. His plans are for you to prosper and not to harm you. I had also begun to pray the Prayer of Jabez at this time.
My second piece of advise is to have your husband post his resume on Monster.com. I finally did (I didn't think it would help since I am in a very specialized profession) and within days a company from California called with an offer for a position on a project they had directly across the street from my old job. I know this job came from God because I would have never applied for a job with this company located in California...I didn't know they had offices in Georgia. The call came from them to me and the job couldn't have been more tailored to my experiences than if I had written the job description myself!
Go on the trip and use it as therapy for the stress you are going through right now. Make the best of it you can and conserve where you can, but don't put a damper on everything worrying about money. When you get back focus on your husbands career and look for what God's will is for your family.
Everything will work out in time and when it does, you will know that everything worked out for the best. My prayers are with you and your husband.
