> For example, on average I would assume most women prefer a romantic getaway to the Maldives over climbing a volcano in Iceland. And most people with kids likely won't be going on a month long roadtrip through Africa or South-America.

Because a romantic getaway is far cheaper than Iceland or Africa. It's not because it's outside their comfort zone, it's because they can't afford it. The average woman (or man) can barely take enough vacation days, let alone pay for it.
