There’s an award-winning doctoral dissertation in marketing, hospitality or behavioral economics to be done on why the world’s most luxurious hotels insist on charging their guests extra for WiFi. It can’t be to build customer loyalty; people loathe it. Surveys suggest patrons paying over $300/night despise paying an additional $10 to $15 a day for internet access (often far more in Europe). You’d think classy chains like the Four Seasons, Ritz-Carlton and Rosewood wouldn’t nickel-and-dime their patrons. You’d think wrong.
