Take your cruise and try not to think about what is happening back home.
Ride out the economic storm, it will get better. We had a similar crisis in the 70s and 80s (not as significant as now, but now is the blame of bad mortgage loans, abuse of position, etc.) and things leveled out with time. If you are young, you have time to recover the losses of your retirement account. When you do recover some, my advice would be to transfer a portion to a guaranteed interest instead of high risk. Won't make as much money, but when the market has a down-side, you won't lose as much.
