If we consider that the influence of travel companions is a higher category than the choice of destination, then a solo traveler would not have a selection process, which is not logical.
For me, it's simple: if my friends want to go to Ibiza and my budget does not allow it, then I do not join them.
If financial constraints take precedence, then the destination is chosen based on my means, regardless of who I am with.
If we do not first manage our own expenses and desires, we risk ending up with regrets or a destination that does not match.
