Like, if you want to see a rain forest or a thousand year old Buddhist temple or a pyramid, there's not really a substitute in the continental US.

But if you've two options, where you can go to the pretty good option domestically or drive past it and continue on to the much better option in another country ... most people will be happy with the closer option, even if there's some small number of people who want the best or have seen all the closer options before and want something different or just whimsically like the idea of going to the further-away one none of their friends have been to.
