World's full of 2nd-tier places to visit that are damn near as good as 1st-tier, but have 1-5% the visitors, putting them way the lead, experience-wise, except for taking instantly-recognizable "I been thar!" photos.

World population should level off before those 2nd-tier ones start to get swamped, too. So that's nice.

Believe it or not, they have got worse based on my experiences in the 80s versus now. Think about it - whole regions of the world were effectively shut out of tourism either by economics or politics back then e.g. China, India, Soviet Union.
