Adding personal time to a work trip, sometimes called bleisure, can turn a draining schedule into something restorative. The trick is keeping the two parts cleanly separated so neither the work nor the finances get muddy.
Confirm the policy before you book anything. Understand which costs remain business, which become personal, and where the trip officially ends. Draw that line clearly and the extension is a gift rather than a gray area.
Protect the work portion first. Deliver everything the trip was for, then start the personal days. When the professional obligations are genuinely complete, the extra time actually recharges you instead of nagging at you.
