Hattie will have to confirm this but I believe the Victorians paved the whole idea of foreign travel, hotels vacations etc.
It was very exclusive and only for the rich.
Now-a-days EVERYBODY takes vacations in foreign lands.
It's very middle class, even lower class (Cancun, Club Med etc.)
So what the rich pay for today is privacy.
You pay for not having to look at middle class people in their bathing suits.
Private little islands like Cap Juluca with private little villas with private little pools. (We even had a private little solarium to sun bath...
privately of course).
When you check in they tell you that there are no locks on the doors at Cap Juluca. (And there aren't!)
You see, there are only rich people and locks are not necessary.
There is a small airport for people to land their private jets (and not see tacky people flying business class).
As the planet gets more and more crowded privacy is more and more valuable.
