CabinThe four hot nights
On one Caribbean cruise our air conditioning failed. Tom and I spent four hot nights assuming it would sort itself out. By the fourth night we were neither cool nor charitable. Now I report cabin problems early, note when I reported them, and follow up politely.
Port daysCozumel, then Roatán
My phone changed itself to local time in port and nearly made us late, once in Cozumel and more recently in Roatán, with about twenty minutes to get back. The phone wasn't malicious. It just didn't understand my priorities.
ExtrasTen years of drink packages
I bought drink packages for roughly ten years. It was easy, which isn't the same as valuable. We even felt faintly obligated to order something, because otherwise the package seemed to be judging us.
PriceThe fare I didn't recheck
I once overpaid for a cruise because I booked the fare, felt relieved, and stopped looking. Now I recheck it, and I count the whole trip, not just the number designed to make me click.
