I mean, that’s fine. But also it implies significant generational family wealth.

The point is that Kevin’s family is loaded. Dad’s likely an investment banker, mid-level corporate executive, white shoe lawyer, or other high income profession. And he comes from a family with similar wealth and status, such that they can afford to shell out five figures on an extended vacation abroad.

I think this is alluded to in the class character of Kevin himself, who seems fairly comfortable playing the spoiled rich kid, but is initially terrified and disoriented when presented with people living in poverty.
