Each theme is scored on what diarists actually wrote after the trip, not before it: how often a place was recommended without reservation, how specific the praise was, whether people said they would return, and how many regrets were logged (weather, crowds, cost, logistics). Editors then verify the practical details — airport, season, stay strategy — against operator sources. Rankings are refreshed as new diaries come in.
