My sister is absolutely hooked on cruises. The amount of money she spends (even at the expense of leaving something for her children heirs) is enormous. Two, three, four times year sometimes. For YEARs she’s been doing it. Even during Covid. I just don’t get the fascination.
She’s two years older than me and she drags her poor husband (who isn’t well himself - impending Alzheimer’s) to carry the bags and push her wheelchair when she needs it. Even when she’s home it’s only to go see all her doctors and search out a new cruise to book. $15K? Go find a lake and buy a boat and sit on it.
