A vacation that also fulfills other obligations, usually those dealing with family or work.
I am taking my kids on an oblication to Miami where I have a conference to attend. We are spending our oblication at my parents place so that they can see their grandkids.

An out-of-town trip that looks like a vacation, but is really done to fulfill an obligation.
We're taking our annual oblication to our in-law's cabin in the woods.

Time taken off from work or other aspects of everyday life to fulfill a personal or social obligation, such as traveling home for a family event, attending a wedding or baby shower, or participating in a ceremonial gathering; a vacation undertaken because you’re obligated to be there.
I’m taking Friday off to fly home for my sister’s baby shower, but it’s definitely an oblication, not a vacation
