Theme	Supporting quotation
Local knowledge is selective and often kept private	“It's more that we forget rather than never knowing.” — necrobrit
Over‑tourism and influencer hype can turn beloved spots into crowded traps	“The locals are living their lives on an organic cadence. They will certainly know entertaining things to do, but it's literally not their job to entertain tourists.” — lorecore
Authentic experiences come from genuine interaction with the right locals	“this, you need to find the active locals that care about their community. the curious ones that like to explore and they will tell you. i could show you places in vienna that no tourist has ever seen, right in the center of town.” — em-bee
