1. sort vacation destinations based on actually wanting to go there, and then filter based on ability-to-go;

2. sort vacation destinations based on ability-to-go, and then pick the top one.

AFAIK, there’s no correlation between wealth/class and which algorithm people use. Rich people are sometimes rich because they’re thrifty, and so are no less likely to employ algorithm #2; poor people are sometimes poor because they tend to splurge on the things they want whenever they come into money, and so are no less likely to employ algorithm #1.

My point is rather that people who employ algorithm #2—regardless of who they are—tend to not actually care about the place they’re going to (since they never had it in mind to go there at all, never did any research or looked forward to visiting, etc.); and that, by making tourism as cheap as possible, Iceland is encouraging people who employ algorithm #2 to visit, without really increasing the number of people who visit due to employing algorithm #1 (who, presumably, are the ones they’d actually like to have as tourists.)
