Should every family pay their own way on vacation?

I have two sisters, and while neither of them has kids, I can still understand why this kind of disagreement happens. Family vacations always sound simple when you’re throwing ideas around in a group chat, but the second money enters the conversation, everyone starts looking at things from a different perspective. It’s rarely about being cheap. Most of the time, it’s about what feels fair.

Personally, I don’t think it’s unreasonable for each family to cover their own costs. If one sibling is traveling alone, another is bringing a partner, and someone else is showing up with six kids, splitting everything evenly between the siblings doesn’t really reflect how much space and resources each group is using. That becomes even harder to justify when two of those children are already adults. At that point, they’re perfectly capable of paying their own share or deciding whether the trip fits their budget.

I also think about the siblings or relatives who don’t have children. There are always a few aunts or uncles in every family who show up on these trips without a big group behind them. Why should they end up paying extra just because someone else has a larger family? It doesn’t seem fair to expect child-free relatives to subsidize everyone else’s vacation simply because they’re related.

To me, the easiest solution is also the simplest one: every family pays for itself. If your household has two people, you pay for two. If your household has eight, you pay for eight. That removes a lot of unnecessary resentment before the trip even begins. Vacations are supposed to bring families together, not create arguments over who owes what before anyone has even packed a suitcase.
