I am not familiar with packages--so even if you lost maybe a portion of the package, it would be better than going without all that money that you could use right now. I would be inclined to accept up to a 50% loss depending on the cost of the whole trip and what my job prospects were in addition to the ability to sustain my family.
DH lost his job Nov 1--he did end up getting a new job Dec 1 (out of state)--we had to cancel a trip to California for money reasons--mostly b/c we needed the ticket credits to be able to see daddy during our transition time. For a very short period--we did not know how to stretch ourselves for 6 months. We ended up getting a modification on our mortgage and setting ourselves up for a long term unemployment--just in case.
Some Trip Insurances include job loss in their contract--so if you had that, I would be checking my insurance first.
Having gone through a job loss and the fear of "what's going to happen now"--I would decide fairly quickly how this trip figures into the entire equation of housing and feeding your family.
It is quite easy to suggest to just take the trip anyway since it is paid for. But feeding my kids for a week on vacation at the possible expense of feeding them for 2-3-4 weeks at home, is just something that cannot be ignored.
But if you find that on the homefront, your family has the financial solvency to get through the next 6-9 months in the event DH cannot become reemployed (or he becomes reemployed at a lower salary)--then it would be quite okay to take the trip.
So--
1. I would immediately ascertain my home situation and my ability to pay bills and such (with severance, emergency funds, and unemployment). Make necessary adjustments that allow the pennies to stretch farther.
2. Do what I Can to make the trip more affordable. (I'd not necessarily cancel a dining plan...maybe cut back to CS or something.)
3. Cancel the trip if I could get at least half the money back (or postpone the trip)--if going on the trip compromises the ability to care for my family in the near future.
HTH--It sucks, just keep your chin up and tell DH to be open to any job prospect that he can find. One of DH's co-workers is insisting on staying locally and is finding out that he may be out of work for the long haul. While it sucks to have DH away--it is nice to know that he found a very secure position and the company is doing their best to work with us, knowing that relocation of all of us is very tough right now.
On the airlines--depending on who you fly, while they have a no-refund policy in most cases, they do allow you to slide tickets out and use the credits. (So DH now flies SW a lot--we had a change in our home schedule and 4 days before he was supposed to come home for a weekend, he was able to rebook his ticket to a better time period that we needed him home and then got a credit for a future ticket b/c that ticket was cheaper than what he had originally booked.)
If you have trip insurance--this could all be a non-issue.




During this difficult time and my prayers and thoughts to your family as you embark on a new journey.
