Which would you do?
Let's say you have the dreaded credit card debt. (Yes, you were stupid at one point in your life, but now you are committed to paying off your debt and will be debt-free in 15 months, using Mary Hunt's Rapid-Debt Repayment Program.)
Do you go on a small, very budget-friendly vacation this year or do you hold off and go after your debt is paid off, using your vacation money to put towards your debt? (Postponing vacation would only get you out of debt maybe one month earlier and the difference in interest charges is very small.)
