This is not happening in a vacuum. The reasons are - Instagram inspiring me with beautiful stories of my friends visiting these exotic locales, cheap and easy ways to be a tourist thanks to low cost airlines and AirBnB, ease of spending in local currencies thanks to credit cards and apps where I never have to carry any cash, answers at fingertips for almost any question I might have about venturing to these places.

In short, any desirable place is going to attract hordes of merely affluent tourists thanks to multiple converging tech trends. If you experience any friction in your travel plans, please share. There might be a startup idea in there /s
