They Love Their Cruises
The Golden Age of cruising was between the 1950s and the end of the 1990s. Obviously, this is the time that most Baby Boomers were coming of age, coming into money, and spending it as they wanted to.
Cruises were a sign of peak relaxation and wealth as you can travel the world without a care in the world. Cruises are less popular nowadays, but you'll be damned to not find a Boomer on a cruise ship.
